Additionally, they feature low quiescent current when compared to conventional LDO regulators. Offered in 5-terminal small outline integrated-circuit SOT-23 package, the TPS764xx series devices are ideal for low-noise applications, cost-sensitive designs and 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 by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage is very low—typically 300 mV at 150 mA of load current (TPS76433)—and is directly proportional to the load current. Since the PMOS pass element is a voltage-driven device, the quiescent current is very low (140 µA maximum) and is stable over the entire range of output load current (0 mA to 150 mA). Intended for use in portable systems such as laptops and cellular phones, the low-dropout voltage feature and low-power operation result in a significant increase in system battery operating life. The TPS764xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 µA maximum at T = 25°C.The TPS764xx is offered in 2.5-V, 2.7-V, 2.8-V, 3.0-V, and 3.3-V fixed-voltages.

TPS76425, TPS76427, TPS76428, TPS76430, TPS76433 LOW-POWER LOW-NOISE 150-mA LOW-DROPOUT LINEAR REGULATORS SLVS180B – MARCH 1999 – REVISED MAY 2001 APPLICATION INFORMATION The TPS764xx family of low-noise and low-dropout (LDO) regulators are optimized for use in battery-operated equipment. They feature extremely low noise (50 µV), low dropout voltages, low quiescent current (140 µA), and an enable input to reduce supply current to less than 2 µA when the regulator is turned off. device operation The TPS764xx uses a PMOS pass element to dramatically reduce both dropout voltage and supply current over more conventional PNP-pass-element LDO designs. The PMOS pass element is a voltage-controlled device which, unlike a PNP transistor, does not require increased drive current as output current increases. Supply current in the TPS764xx is essentially constant from no-load to maximum load. Current limiting and thermal protection prevent damage by excessive output current and/or power dissipation. The device switches into a constant-current mode at approximately 1 A; further load reduces the output voltage instead of increasing the output current. The thermal protection shuts the regulator off if the junction temperature rises above 165°C. Recovery is automatic when the junction temperature drops approximately 25°C below the high temperature trip point. The PMOS pass element includes a back diode that safely conducts reverse current when the input voltage level drops below the output voltage level. An internal resistor, in conjunction with external 0.01-µF bypass capacitor, creates a low-pass filter to further reduce the noise. The TPS764xx exhibits only 50 µV of output voltage noise using 0.01 µF bypass and 4.7-µF output capacitors. A logic low on the enable input, EN, shuts off the output and reduces the supply current to less than 2 µA. EN should be tied high in applications where the shutdown feature is not used. A typical application circuit is shown in Figure 19. TPS764xx† 1 VI IN OUT 5 VO C1 4 1 µF 3 BYPASS + EN + 0.01 µF 4.7 µF GND 2 CSR = 1 Ω †TPS76425, TPS76427 TPS76430, TPS76433. Figure 19.

A higher-value electrolytic input capacitor may be necessary if large, fast-rise-time load transients are anticipated and the device is located several inches from the power source. Like all low dropout regulators, the TPS764xx requires an output capacitor connected between OUT and GND to stabilize the internal loop control. The minimum recommended capacitance value is 4.7 µF and the ESR (equivalent series resistance) must be between 0.2 Ω and 10 Ω. Capacitor values 4.7 µF or larger are acceptable, provided the ESR is less than 10 Ω. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described above. Most of the commercially available 4.7 µF surface-mount solid tantalum capacitors, including devices from Sprague, Kemet, and Nichico, meet the ESR requirements previously stated. Multilayer ceramic capacitors should have minimum values of 1 µF over the full operating temperature range of the equipment. CAPACITOR SELECTION PART NO. MFR.

TPS76425, TPS76427, TPS76428, TPS76430, TPS76433 LOW-POWER LOW-NOISE 150-mA LOW-DROPOUT LINEAR REGULATORS SLVS180B – MARCH 1999 – REVISED MAY 2001 APPLICATION INFORMATION power dissipation and junction temperature Specified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature allowable without damaging the device is 150°C. 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 equal to D(max) D P . D(max) The maximum-power-dissipation limit is determined using the following equation: (cid:0)TJmax(cid:1)TA P D(max) R (cid:0)JA Where: TJmax is the maximum allowable junction temperature RθJA 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(cid:2)(cid:3)VI(cid:1)VO(cid:4)(cid:0)IO Power dissipation resulting from quiescent current is negligible. regulator protection The TPS764xx pass element has a built-in back diode that safely conducts reverse current when the input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally limited. If extended reverse voltage is anticipated, external limiting might be appropriate. The TPS764xx also features internal current limiting and thermal protection. During normal operation, the TPS764xx limits output current to approximately 800 mA. 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 165°C, thermal-protection circuitry shuts it down. Once the device has cooled down to below 140°C, regulator operation resumes. 12 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265
