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.

... In this state, the quiescent current is less than 1mA. This pin behaves much like an electronic switch. Power Good The TS9002 includes the Power Good feature. When the output is not within the specified voltage, it pulls low. This can occur under the following conditions: (1) Input Voltage too low. ...
