3 Description

The TPS7A7001 is a high-performance, positivevoltage,

low-dropout (LDO) regulator designed for

applications requiring very low input voltage and very

low dropout voltage at up to 2 A. The device operates

with a single input voltage as low as 1.425 V, and

with an output voltage programmable to as low as 0.5

V. The output voltage can be set with an external

resister divider.

The TPS7A7001 features ultra-low dropout, ideal for

applications where VOUT is very close to VIN.

Additionally, the TPS7A7001 has an enable pin for

further reduced power dissipation while in shutdown

mode. The TPS7A7001 provides excellent regulation

over variations in line, load, and temperature.

The TPS7A7001 is available in an 8-pin SO

PowerPAD™ package.
