These regulators feature low dropout voltages and quiescent currents comparedto conventional LDO regulators. Offered in a 5-terminal, small outline integrated-circuit SOT-23 package, the TPS763xxseries devices are ideal for cost-sensitive designs and for applications where board space is at a premium.A combination of new circuit design and process innovation has enabled the usual pnp pass transistor to be replaced bya PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage is verylow—typically 300 mV at 150 mA of load current (TPS76333)—and is directly proportional to the load current. Since thePMOS pass element is a voltage-driven device, the quiescent current is very low (140 µA maximum) and is stable overthe entire range of output load current (0 mA to 150 mA). Intended for use in portable systems such as laptops and cellularphones, the low-dropout voltage feature and low-power operation result in a significant increase in system battery operatinglife.The TPS763xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 µAmaximum at TJ = 25°C.The TPS763xx is offered in 1.6-V,1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, 3.8-V, and 5-V fixed-voltageversions and in a variable version (programmable over the range of 1.5 V to 6.5 V.AVAILABLE OPTIONSTJVOLTAGEVariable1.6 V1.8 V2.5 V−40°C to 125°C2.7 V2.8 V3.0 V3.3 V3.8 V5.0 VSOT-23(DBV)PACKAGEPART NUMBERTPS76301DBVT(1)TPS76316DBVTTPS76318DBVTTPS76325DBVTTPS76327DBVTTPS76328DBVTTPS76330DBVTTPS76333DBVTTPS76338DBVTTPS76350DBVTTPS76301DBVR(2)TPS76316DBVRTPS76318DBVRTPS76325DBVRTPS76327DBVRTPS76328DBVRTPS76330DBVRTPS76333DBVRTPS76338DBVRTPS76350DBVRSYMBOLPAZIPBHIPBAIPBBIPBCIPBDIPBIIPBEIPBFIPBGI(1)The DBVT passive indicates tape and reel of 250 parts.(2)The DBVR passive indicates tape and reel of 3000 parts.Please be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.All trademarks are the property of their respective owners.PRODUCTION DATA information is current as of publication date.

LINEAR REGULATORSAPPLICATION INFORMATIONwww.ti.comThe TPS763xx low-dropout (LDO) regulators are new families of regulators which have been optimized for use inbattery-operated equipment and feature extremely low dropout voltages, low quiescent current (140 µA), and an enableinput to reduce supply currents to less than 2 µA when the regulator is turned off.device operationThe TPS763xx uses a PMOS pass element to dramatically reduce both dropout voltage and supply current over moreconventional PNP pass element LDO designs. The PMOS pass element is a voltage-controlled device that, unlike a PNPtransistor, does not require increased drive current as output current increases. Supply current in the TPS763xx isessentially constant from no-load to maximum load.Current limiting and thermal protection prevent damage by excessive output current and/or power dissipation. The deviceswitches into a constant-current mode at approximately 1 A; further load reduces the output voltage instead of increasingthe output current. The thermal protection shuts the regulator off if the junction temperature rises above 165°C. Recoveryis automatic when the junction temperature drops approximately 25°C below the high temperature trip point. The PMOSpass element includes a back diode that safely conducts reverse current when the input voltage level drops below the outputvoltage level.A logic low on the enable input, EN shuts off the output and reduces the supply current to less than 2 µA. EN should betied high in applications where the shutdown feature is not used.A typical application circuit is shown in Figure 20.TPS763xx(1)VI1IN45NC/FBC11 µFOUT3ENGND2VO+4.7 µFCSR = 1 Ω(1)TPS76316, TPS76318, TPS76325, TPS76327, TPS76328,TPS7630 TPS76333, TPS76338, TPS76350 (fixed-voltage options).Figure 20.

A higher-value electrolytic inputcapacitor may be necessary if large, fast-rise-time load transients are anticipated and the device is located several inchesfrom the power source.Like all low dropout regulators, the TPS763xx requires an output capacitor connected between OUT and GND to stabilizethe internal loop control. The minimum recommended capacitance value is 4.7 µF and the ESR (equivalent seriesresistance) must be between 0.3 Ω and 10 Ω. Capacitor values 4.7 µF or larger are acceptable, provided the ESR is lessthan 10 Ω. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, providedthey meet the requirements described above. Most of the commercially available 4.7 µF surface-mount solid tantalumcapacitors, including devices from Sprague, Kemet, and Nichico, meet the ESR requirements stated above.CAPACITOR SELECTIONPART NO.T494B475K016AS195D106x0016x2T695D106x003562TTPSC475K035R0600MFR.KEMETSPRAGUESPRAGUEAVXVALUE4.7 µF10 µF10 µF4.7 µFMAX ESR(1)1.5 Ω1.5 Ω1.3 Ω0.6 ΩSIZE (H × L × W)†1.9 × 3.5 × 2.81.3 × 7.0 × 2.72.5 × 7.6 × 2.52.6 × 6.0 × 3.2(1)Size is in mm.

TPS76301 Adjustable LDO Regulator Programmingpower dissipation and junction temperatureSpecified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature allowableto avoid damaging the device is 150°C. This restriction limits the power dissipation the regulator can handle in any givenapplication. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation,PD(max), and the actual dissipation, PD, which must be less than or equal to PD(max).The maximum-power-dissipation limit is determined using the following equation:Tmax*TAP+JD(max)RqJAWhere:TJmax is the maximum allowable junction temperatureRθJA is the thermal resistance junction-to-ambient for the package, see the dissipation rating table.TA is the ambient temperature.The regulator dissipation is calculated using:PD+V*V IIOOǒǓPower dissipation resulting from quiescent current is negligible.14元器件交易网www.cecb2b.comwww.ti.comTPS76301, TPS76316, TPS76318, TPS76325, TPS76327TPS76328, TPS76330, TPS76333, TPS76338, TPS76350LOWĆPOWER 150ĆmA LOWĆDROPOUT LINEAR REGULATORSSLVS181H − DECEMBER 1998 − REVISED JANUARY 2004APPLICATION INFORMATIONregulator protectionThe TPS763xx pass element has a built-in back diode that safely conducts reverse currents when the input voltage dropsbelow the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internallylimited. If extended reverse voltage is anticipated, external limiting might be appropriate.The TPS763xx also features internal current limiting and thermal protection. During normal operation, the TPS763xx limitsoutput current to approximately 800 mA. When current limiting engages, the output voltage scales back linearly until theovercurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not toexceed the power dissipation ratings of the package. If the temperature of the device exceeds 165°C, thermal-protectioncircuitry shuts it down. Once the device has cooled down to below 140°C, regulator operation resumes.15元器件交易网www.cecb2b.com
