TS9001

300mA CMOS Low Dropout Voltage Regulator with Enable

Low Drop Out Voltage 0.4V

Enable Shutdown

General Description

The TS9011 series is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent

current (30uA typ.), low dropout voltage, and high output voltage accuracy, making them ideal for battery applications.

The Chip Enable (CE) includes a CMOS or TTL compatible input allows the output to be turned off to prolong battery life.

The TS9001 series is included a precision voltage reference, error correction circuit, a current limited output driver, over

temperature shutdown, and a reference bypass pin to improve its already excellent low-noise performance.

This series are offered in 5-pin SOT-25 package.
