3 Description
The TPS7A7002 is a high-performance, positivevoltage,
low-dropout (LDO) regulator designed for
use in applications requiring very-low input voltage
and very-low dropout voltage at up to 3 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 TPS7A7002 features ultra-low dropout, ideal for
applications where VOUT is very close to VIN.
Additionally, the TPS7A7002 has an enable pin for
further reduced power dissipation while in Shutdown
mode. The TPS7A7002 provides excellent regulation
over variations in line, load, and temperature.
The TPS7A7002 is available in an 8-pin SO
PowerPAD™ package.
