TPS752xxQ TPS754xxQ www.ti.com SLVS242C–MARCH2000–REVISEDOCTOBER2007 DESCRIPTION, CONTINUED The RESET (SVS, POR, or power on reset) output of the TPS752xxQ initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS752xxQ monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage. When the output reaches 95% of its regulated voltage, RESET goes to a high-impedance state after a 100-ms delay. RESET goes to a logic-low state when the regulated output voltage is pulled below 95% (that is, during an overloadcondition)ofitsregulatedvoltage. The TPS754xxQ has a power good terminal (PG) as an active high, open drain output for use with a power-on resetoralow-batteryindicator. The TPS754xxQ and TPS752xxQ are offered in 1.5 V, 1.8 V, 2.5 V and 3.3 V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5 V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS754xxQ and TPS752xxQ families are availableina20-pinTSSOP(PWP)package. blank This integrated circuit can be damaged by ESD.

TPS752xxQ TPS754xxQ www.ti.com SLVS242C–MARCH2000–REVISEDOCTOBER2007 APPLICATION INFORMATION The TPS752xxQ and TPS754xxQ devices include four fixed-output voltage regulators (1.5 V, 1.8 V, 2.5 V and 3.3V),andanadjustableregulator,theTPS75x01Q(adjustablefrom1.5Vto5V). Minimum Load Requirements The TPS752xxQ and TPS754xxQ families are stable even at zero load; no minimum load is required for operation. Pin Functions Enable(EN) The EN terminal is an input that enables or shuts down the device. If EN is a logic high, the device is in shutdownmode.WhenENgoestologiclow,thenthedeviceisenabled. Power-Good(PG)—TPS754xxQ The PG terminal is an open drain, active high output that indicates the status of V (output of the LDO). When OUT V reaches 83% of the regulated voltage, PG goes to a high impedance state. It goes to a low-impedance OUT state when V falls below 83% (that is, an overload condition) of the regulated voltage. The open drain output OUT ofthePGterminalrequiresapullupresistor. Sense(SENSE) The SENSE terminal of the fixed output options must be connected to the regulator output, and the connection should be as short as possible. Internally, SENSE connects to a high-impedance wide-bandwidth amplifier through a resistor-divider network, and noise pickup feeds through to the regulator output. It is essential to route the SENSE connection in such a way to minimize/avoid noise pickup. Adding RC networks between the SENSE terminal and V to filter noise is not recommended because these types of networks may cause the regulator OUT tooscillate. Feedback(FB) FB is an input terminal used for the adjustable-output options and must be connected to an external feedback resistor divider. The FB connection should be as short as possible. It is essential to route it in such a way to minimize/avoid noise pickup. Adding RC networks between FB terminal and V to filter noise is not OUT recommendedbecausethesetypesofnetworksmaycausetheregulatortooscillate. Reset(RESET)—TPS752xxQ The RESET terminal is an open drain, active low output that indicates the status of V . When V reaches OUT OUT 95% of the regulated voltage, RESET goes to a high-impedance state after a 100-ms delay. RESET goes to a low-impedance state when V is below 95% of the regulated voltage. The open-drain output of the RESET OUT terminalrequiresapullupresistor. GND/HEATSINK All GND/HEATSINK terminals are connected directly to the mount pad for thermal-enhanced operation. These terminalscouldbeconnectedtoGNDorleftfloating. InputCapacitor For a typical application, an input bypass capacitor (0.22 μF to 1 μF) is recommended for device stability. This capacitor should be as close to the input pins as possible. For fast transient conditions where droop at the input of the LDO may occur because of high inrush current, it is recommended to place a larger capacitor at the input aswell.Thesizeofthis capacitor depends on the output current and response time of the main power supply, as wellasthedistancetotheload(LDO). 14 SubmitDocumentationFeedback Copyright©2000–2007,TexasInstrumentsIncorporated

TPS752xxQ TPS754xxQ www.ti.com SLVS242C–MARCH2000–REVISEDOCTOBER2007 OutputCapacitor As with most LDO regulators, the TPS752xxQ and TPS754xxQ require an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance value is 47 μF and theESR (equivalent series resistance) must be between 100 mΩ and 10 Ω. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described in thissection.Largercapacitorsprovideawiderrangeofstabilityandbetterloadtransientresponse. This information, along with the ESR graphs (see Figure 20 and Figure 21), is included to assist in selection of suitable capacitance for the user’s application. When necessary to achieve low height requirements along with high output current and/or high load capacitance, several higher ESR capacitors can be used in parallel to meet theseguidelines. ESR and Transient Response LDOs typically require an external output capacitor for stability. In fast transient response applications, capacitors are used to support the load current while the LDO amplifier is responding. In most applications, one capacitor is usedtosupportbothfunctions. Besides its capacitance, every capacitor also contains parasitic impedances. These parasitic impedances are resistive as well as inductive. The resistive impedance is called equivalent series resistance (ESR), and the inductive impedance is called equivalent series inductance (ESL).

TPS752xxQ TPS754xxQ www.ti.com SLVS242C–MARCH2000–REVISEDOCTOBER2007 In steady state operation (dc state condition), the load current is supplied by the LDO (solid arrow) and the voltage across the capacitor is the same as the output voltage (V(C ) = V ). This condition means that no OUT OUT current is flowing into the C branch. If I suddenly increases (that is, a transient condition), the following OUT OUT eventsoccur: • The LDO is not able to supply the sudden current need because of its response time (t in Figure 24). 1 Therefore, capacitor C provides the current for the new load condition (the dashed arrow). C now acts OUT OUT like a battery with an internal resistance, ESR. Depending on the current demand at the output, a voltage dropoccursatR .ThisvoltageisshownasV inFigure23.

As a result OUT OUT OUT ESR of the discharge of C , the output voltage V drops continuously until the response time t of the LDO is OUT OUT 1 reached and the LDO resumes supplying the load.

DIE (a)SideView Thermal Pad DIE (b)EndView (c)BottomView Figure26.ViewsofThermally-EnhancedPWPPackage Traditionally, surface mount and power have been mutually exclusive terms. A variety of scaled-down TO220-type packages have leads formed as gull wings to make them applicable for surface-mount applications. These packages, however, suffer from several shortcomings: they do not address the very low profile requirements (less than 2 mm) of many of today’s advanced systems, and they do not offer a pin-count high enough to accommodate increasing integration. On the other hand, traditional low-power surface-mount packages require power dissipation derating that severely limits the usable range of many high-performance analogcircuits.

TPS752xxQ TPS754xxQ www.ti.com SLVS242C–MARCH2000–REVISEDOCTOBER2007 The PWP package is designed to optimize the heat transfer to the PWB. Because of the very small size and limited mass of a TSSOP package, thermal enhancement is achieved by improving the thermal conduction paths that remove heat from the component. The thermal pad is formed using a lead-frame design (patent pending) and manufacturing technique to provide the user with direct connection to the heat-generating IC. When this pad is soldered or otherwise coupled to an external heat dissipator, high power dissipation in the ultra-thin, fine-pitch, surface-mountpackagecanbereliablyachieved. Because the conduction path has been enhanced, power-dissipation capability is determined by the thermal considerationsinthePWBdesign.Forexample,simplyadding a localized copper plane (heatsink surface) that is coupled to the thermal pad enables the PWP package to dissipate 2.5 W in free air (see Figure 28(a), 8 cm2 of copper heatsink and natural convection). Increasing the heatsink size increases the power dissipation range for the component. The power dissipation limit can be further improved by adding airflow to a PWB/IC assembly (see Figure 27 and Figure 28). The line drawn at 0.3 cm2 in Figure 27 and Figure 28 indicates performance at theminimumrecommendedheatsinksize,illustratedinFigure30. The thermal pad is directly connected to the substrate of the IC, which for the TPS752xxQPWP and TPS754xxQPWP series is a secondary electrical connection to device ground. The heat-sink surface that is addedtothePWPcanbea ground plane or left electrically isolated. In TO220-type surface-mount packages, the thermal connection is also the primary electrical connection for a given terminal which is not always ground. The PWP package provides up to 16 independent leads that can be used as inputs and outputs.

TPS752xxQ TPS754xxQ www.ti.com SLVS242C–MARCH2000–REVISEDOCTOBER2007 Figure 29 is an example of a thermally-enhanced PWB layout for use with the new PWP package. This board configuration was used in the thermal experiments that generated the power ratings shown in Figure 27 and Figure 28. As discussed earlier, copper has been added on the PWB to conduct heat away from the device. R θJA for this assembly is illustrated in Figure 27 as a function of heatsink area. A family of curves is included to illustratetheeffectofairflowintroducedintothesystem. HeatsinkArea 1 oz Copper Boardthickness 62mils (0.15748 cm) Board size 3.2 in. x 3.2 in.

A P should then be applied to the internal power dissipated by the TPS75433QPWP regulator. The equation D(max) forcalculatingtotalinternalpowerdissipationoftheTPS75433QPWPis: P = (V -V )´I + V ´I D(total) IN OUT OUT IN Q (6) Because the quiescent current of the TPS75433QPWP is very low, the second term is negligible, further simplifyingtheequationto: P = (V -V )´I D(total) IN OUT OUT (7) For the case where T = +55(cid:176) C, airflow = 200 ft/min, copper heat-sink area = 4 cm2, the maximum A power-dissipation limit can be calculated. First, from Figure 27, we find the system R is 50(cid:176) C/W; therefore, the θJA maximumpower-dissipationlimitis: P = TJ(Max)-TA =125°C-55°C = 1.4 W D(Max) RqJA(System) 50°C/W (8) If the system implements a TPS75433QPWP regulator, where V = 5 V and I = 800 mA, the internal power IN OUT dissipationis: P = (V -V )´I = (5-3.3)´0.8 = 1.36 W D(total) IN OUT OUT (9) Comparing P with P reveals that the power dissipation in this example does not exceed the calculated D(total) D(max) limit. When it does, one of two corrective actions should be made: either raise the power-dissipation limit by increasing the airflow or the heat-sink area, or loweri the internal power dissipation of the regulator by reducing the input voltage or the load current. In either case, the above calculations should be repeated with the new systemparameters. Copyright©2000–2007,TexasInstrumentsIncorporated SubmitDocumentationFeedback 21
