TS9002
TS9002 is 300mA CMOS LDO manufactured by Taiwan Semiconductor.
Description
The TS9002 series is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (30u A typ.), low dropout voltage, and high output voltage accuracy, making them ideal for battery applications. The Chip Enable (CE) includes a CMOS or TTL patible 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.
Features
Dropout voltage typically 0.4V@Io=300m A (Vo>2.5V) Low power consumption Output voltage +/-2%, +/-3% (1.2V) Internal current limit and thermal shutdown Short circuit current fold-back Power saving shutdown mode Power good output function
