Product Description
The CM3102 is a low quiescent current (90uA) regula-
tor 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 inter-
nal discharge MOSFET resistance (500
) will force the
output to ground whenever the device has been shut-
down.
The CM3102 is fully protected, offering both overload
current limiting and high temperature thermal shut-
down.
Available in a tiny SOT23 package, the device is ideal
for space critical applications.
The CM3102 is available with optional lead-free finish-
ing.
