The TPS76915T low-dropout (LDO) voltage regulators offers the benefits of low dropout voltage, ultralow-power operation, and miniaturized packaging. These regulators TPS76915T feature low dropout voltages and ultralow quiescent current compared to conventional LDO regulators. Offered in a 5-terminal small outline integrated-circuit SOT-23 package, the TPS76915T series devices are ideal for micropower operations and 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 of TPS76915T behaves as a low-value resistor, the dropout voltage is very low, typically 71 mV at 100 mA ofload current (TPS76950), and is directly proportional to the load current. Since the PMOS pass element is a
voltage-driven device, the quiescent current of TPS76915T  is ultralow (28 µA maximum) and is stable over the entire range of output load current (0 mA to 100 mA). Intended for use in portable systems such as laptops and cellular phones, the ultralow-dropout voltage feature and ultralow-power operation of TPS76915T result in a significant increase in system battery operating life.

The TPS76915T also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 µA typical at T_J = 25°C. The TPS769xx is offered in 1.2-V, 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5-V fixed-voltage versions and in a variable version (programmable over the range of 1.2 V to 5.5 V).
