100mA Low Dropout Adjustable Voltage Regulator

Description

The GSCLM2931 positive voltage regulator features a very low quiescent current of 1mA or less when supplying 10mA loads. This unique

characteristic and the extremely low input-output differential required for proper regulation (0.2V for output current of 10mA) make the

GSCLM2931 the ideal regulator for standby power system. Applications include memory standby circuits, COMS and other low power

processor power supplies as well as systems demanding as much as 100mA of output current.

Designed originally for automotive applications, the GSCLM2931 and all regulated circuitry are protected from reverse battery installations

or 2 battery jumps. During line transients, such as a load dump(60V) when the input voltage to the regulator can momentarily exceed the

specified maximum operating voltage, the regulator will automatically shut down to protect both internal circuits and the load. The

GSCLM2931 cannot be harmed by temporary mirror-image insertion. Familiar regulator features such as short circuit and thermal overload

protection are also provided.
