DESCRIPTION
The TPS7A7001 is a high-performance, positive-
voltage, low-dropout (LDO) regulator designed for
use in 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 using an
external divider.
The TPS7A7001 features ultralow dropout, ideal for
applications where V_OUT is very close to V_IN.
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 SOIC-8
PowerPAD™ package.
