Product Description
The CM3102 is a low quiescent current (90uA) regulator that delivers up to 150mA of load current at a fixed 1.2V output. In addition, the CM3102 features a Power Good output signal (PG) that goes open drain 1 to 5 ms after the output
voltage has exceeded typically 93% of its nominal level. A dedicated control input (EN, Active High) has been included for power-up sequencing flexibility. When this input is taken low, the regulator is disabled. In this state, the supply current will drop to near zero. An internal discharge
MOSFET resistance (500Ω) will force the output to ground whenever the device has been shutdown. The CM3102 is fully protected, offering both overload current limiting and high temperature thermal shutdown. Available in a tiny SOT23 package, the device is ideal for space critical applications. The CM3102 is available with optional lead-free finishing.
