FEATURES  
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.

Input Voltage as low as 1.425 V  
380 mV Dropout Maximum at 2 A  
Adjustable Output from 0.5 V  
Protections: Current Limit and Thermal  
Shutdown  
Enable Pin  
1-µA Quiescent Current in Shutdown Mode  
Full Industrial Temperature Range  
The TPS7A7001 features ultralow 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.  
Available in SOIC-8, Fully RoHS-Compliant  
Package  
APPLICATIONS
