TS9002

300mA CMOS LDO with Enable & Power Good

Low Drop Out Voltage 0.4V

Enable Shutdown

Power Good

General Description

The TS9002 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 TS9002 series is included a precision voltage reference, error correction circuit, a current limited output driver, over

temperature shutdown, and a “Power Good” detector, which pulls low when the output is out of regulation.

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