TPS715 SLVS338R–MAY2001–REVISEDAPRIL2015 www.ti.com 7 Detailed Description 7.1 Overview The TPS715 family of LDOs consume only 3.2 µA of current while offering a wide input voltage range and low- dropout voltage in a small package. The devices, which operate over an input range of 2.5 V to 24 V, are stable with any capacitor greater than or equal to 0.47 μF. The low quiescent current makes the TPS715 ideal for powering battery management ICs. Specifically, because the TPS715 is enabled as soon as the applied voltage reaches the minimum input voltage, the output is quickly available to power continuously operating battery chargingICs. 7.2 Functional Block Diagrams V(IN) V(OUT) Current Sense Leakage Null ILIM Control Circuit R1 _ + GND FB R2 V = 1.205 V ref Bandgap Reference Figure10.

TPS715 www.ti.com SLVS338R–MAY2001–REVISEDAPRIL2015 8.2.2 DetailedDesignProcedure 8.2.2.1 ExternalCapacitorRequirements Although not required, a 0.047-μF or larger input bypass capacitor, connected between IN and GND and located close to the device, is recommended to improve transient response and noise rejection of the power supply as a whole.Ahigher-valueinputcapacitormaybenecessaryiflarge,fast-rise-timeloadtransientsareanticipatedand thedeviceislocatedseveralinchesfromthepowersource. TheTPS715requiresanoutputcapacitorconnectedbetweenOUTandGNDtostabilizetheinternalcontrolloop. Anycapacitor(includingceramicandtantalum)greaterthanorequalto0.47 μFproperlystabilizesthisloop.X7R or X5R type capacitors are recommended due to their wider temperature spec and lower temperature coefficient, butothertypesofcapacitorsmaybeused. 8.2.2.2 DropoutVoltage(V ) DO Generally speaking, the dropout voltage often refers to the voltage difference between the input and output voltage (V = V – V ). However, in the Electrical Characteristics, V is defined as the V – V voltage at DO IN OUT DO IN OUT the rated current, where the pass-FET is fully on in the ohmic region of operation and is characterized by the classic R of the FET. V indirectly specifies a minimum input voltage above the nominal programmed DS(on) DO output voltage at which the output voltage is expected to remain within its accuracy boundary. If the input falls belowthisV limit(V <V +V ),thentheoutputvoltagedecreasesinordertofollowtheinputvoltage. DO IN OUT DO Dropout voltage is always determined by the R of the main pass-FET. Therefore, if the LDO operates below DS(on) theratedcurrent,thentheV forthatcurrentscalesaccordingly.R canbecalculatedusingEquation1: DO DS(on) V R = DO DS(ON) I RATED (1) 8.2.2.3 SettingV fortheTPS71501AdjustableLDO OUT The TPS715 family contains an adjustable-version, TPS71501, which sets the output voltage using an external resistor divider as shown in Figure 13. The output voltage operating range is 1.2 V to 15 V, and is calculated using: æ R1ö VOUT = VREF´çè1+R2÷ø where • V =1.205V(typical) (2) REF Resistors R1 and R2 should be chosen to allow approximately 1.5-μA of current through the resistor divider. Lower value resistors can be used for improved noise performance, but will consume more power. Higher resistor values should be avoided as leakage current into or out of FB across R1/R2 creates an offset voltage that is proportional to V divided by V . The recommended design procedure is to choose R2 = 1MΩ to set OUT REF thedividercurrentat1.5 μA,andthencalculateR1usingEquation3: æV ö R1=ç OUT -1÷´2 V è REF ø (3) Figure13showsthisconfiguration.

TPS715 www.ti.com SLVS338R–MAY2001–REVISEDAPRIL2015 10 Layout 10.1 Layout Guidelines For best overall performance, place all circuit components on the same side of the printed-circuit-board and as nearaspracticaltotherespectiveLDOpinconnections.Placegroundreturnconnectionsfortheinputandoutput capacitors as close to the GND pin as possible, using wide, component-side, copper planes. TI strongly discourages using vias and long traces to create LDO circuit connections to the input capacitor, output capacitor, or the resistor divider because that will negatively affect system performance. This grounding and layout scheme minimizes inductive parasitics, and thereby reduces load-current transients, minimizes noise, and increases circuit stability. A ground reference plane is also recommended and is either embedded in the PCB itself or locatedonthebottomsideofthePCBoppositethecomponents.Thisreferenceplaneservestoassureaccuracy oftheoutputvoltageandshieldtheLDOfromnoise. 10.2 Layout Example GND R2 NC GND FB CIN TPS71501DCK R1 VIN IN OUT COUT GND VOUT Figure17.

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 Orderable Device Status Package Type Package Pins Package Eco Plan Lead/Ball Finish MSL Peak Temp Op Temp (°C) Device Marking Samples (1) Drawing Qty (2) (6) (3) (4/5) TPS71550DCKRG4 ACTIVE SC70 DCK 5 3000 Green (RoHS NIPDAU Level-1-260C-UNLIM -40 to 125 T48 & no Sb/Br) (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs. 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.
