DESCRIPTION

The TPS76901 low-dropout (LDO) voltage regulator offers the benefits of low dropout voltage, ultralow-power

operation, and miniaturized packaging. This regulator features low dropout voltages and ultralow quiescent

current compared to conventional LDO regulators. The TPS76901 is 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 behaves as a low-value resistor, the

dropout voltage is very low, and is directly proportional to the load current. Since the PMOS pass element is a

voltage-driven device, the quiescent current 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 result in a significant increase in system

battery operating life.

The TPS76901 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current

to 1 μA, typical at T

= 25°C. The TPS76901 is a variable version programmable over the range of 1.2 V to

4.5 V.
