Output 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. 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 Power saving shutdown mode Power good output function Ordering Information Part No. Operating Temp.
