3 Description
The TPS7A7001 is a high-performance, positive-
voltage, 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 SO-8 PowerPADâ¢
package.
