Product Description
The CM3112-12 is a low quiescent current (90uA) regulator that delivers up to 150mA of load current at a fixed 1.2V output. All the necessary circuitry has been included to deliver a 50Ω power good signal (open drain) which remains for 5ms after the output has exceeded 90% (typ) of its nominal level.
