DEVICE OPERATION The TPS766xx features very low quiescent current that remains virtually constant even with varying loads. Conventional LDO regulators use a pnp pass element, the base current of which is directly proportional to the load current through the regulator (I = I /b ). The TPS766xx uses a PMOS transistor to pass current; because B C thegateofthePMOSisvoltagedriven,operatingcurrentislowandinvariableoverthefullloadrange. Another pitfall associated with the pnp pass element is its tendency to saturate when the device goes into dropout. The resulting drop in b forces an increase in I to maintain the load. During power up, this increase in I B B translates to large start-up currents. Systems with limited supply current may fail to start up. In battery-powered systems, it means rapid battery discharge when the voltage decays below the minimum required for regulation. TheTPS766xxquiescentcurrentremainslowevenwhentheregulatordropsout,eliminatingbothproblems. The TPS766xx family also features a shutdown mode that places the output in the high-impedance state (essentially equal to the feedback-divider resistance) and reduces quiescent current to 1 m A (typ). If the shutdown feature is not used, EN should be tied to ground. Response to an enable transition is quick; regulated outputvoltageisreestablishedintypically160m s. MINIMUM LOAD REQUIREMENTS TheTPS766xxfamilyisstableevenatzeroload;nominimumloadisrequiredforoperation. FB—PIN CONNECTION (ADJUSTABLE VERSION ONLY) The FB pin is an input pin to sense the output voltage and close the loop for the adjustable option. The output voltage is sensed through a resistor divider network to close the loop as shown in Figure 29. Normally, this connection should be as short as possible; however, the connection can be made near a critical circuit to improve performance at that point. Internally, FB connects to a high-impedance, wide-bandwidth amplifier and noise pickup feeds through to the regulator output. Routing the FB connection to minimize or avoid noise pickup isessential. EXTERNAL CAPACITOR REQUIREMENTS An input capacitor is not usually required; however, a ceramic bypass capacitor (0.047 m F or larger) improves load transient response and noise rejection if the TPS766xx is located more than a few inches from the power supply. A higher-capacitance electrolytic capacitor may be necessary if large (hundreds of milliamps) load transientswithfastrisetimesareanticipated. Like most low dropout regulators, the TPS766xx requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance value is 4.7 m F and the ESR (equivalent series resistance) must be between 300 mW and 20 Ω. Capacitor values 4.7 m F or larger are acceptable, provided the ESR is less than 20 Ω. Solid tantalum electrolytic and aluminum electrolytic capacitors are all suitable, provided they meet the requirements described previously. Ceramic capacitors, with series resistorsthataresizedtomeetthepreviouslydescribedrequirements,mayalsobeused. 14 SubmitDocumentationFeedback Copyright©1999–2009,TexasInstrumentsIncorporated ProductFolderLink(s):TPS76615TPS76618 TPS76625 TPS76627 TPS76628 TPS76630TPS76633 TPS76650 TPS76601

The internal comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal regulated value, the PG output transistor turns on, taking the signal low. The open-drain output requires a pullup resistor. If not used, it can be left floating. PG can be used to drive power-on reset circuitry or used as a low-batteryindicator. REGULATOR PROTECTION The TPS766xx PMOS-pass transistor has a built-in back diode that conducts reverse currents when the input voltage drops below the output voltage (for example, during power down). Current is conducted from the output to the input and is not internally limited. When extended reverse voltage is anticipated, external limiting may be appropriate. The TPS766xx also features internal current limiting and thermal protection. During normal operation, the TPS766xx limits output current to approximately 0.8 A (typ). When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds +150°C (typ), thermal-protection circuitry shuts it down. Once the device has cooledbelow+130°C(typ),regulatoroperationresumes. POWER DISSIPATION AND JUNCTION TEMPERATURE Specified regulator operation is assured to a junction temperature of +125°C; the maximum junction temperature should be restricted to +125°C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, P , and the actual dissipation, P , which must be less than or D(max) D equaltoP .

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
