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 鈥淧ower Good鈥?detector, which pulls low when the output is out of regulation.
This series are offered in 5-pin SOT-25 package.
Features
Dropout voltage typically 0.4V@Io=300mA (Vo>2.5V)
Low power consumption
Output voltage +/-2%, +/-3% (1.2V)
Internal current limit and thermal shutdown
Short circuit current fold-back
