TPS76430DBVR Datasheet | Texas Instruments

description The TPS764xx family of low-dropout (LDO) voltage regulators offers the benefits of a low noise, low-dropout voltage, low-power operation, and miniaturized package. Additionally, they feature low quiescent current when pared 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 bination 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 m V at 150 m A 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 m A to 150 m A). 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 TJ = 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.
