Description

The GM2123 series of positive, linear regulators feature low quiescent current (30ꢀA typ.) with low dropout

voltage, making them ideal for battery applications.

These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under

the “Worst” of operating conditions.

The GM2123 is stable with an output capacitance of 2.2ꢀF or greater.

certain IOUT value).

4: To prevent the Short Circuit Current protection feature from being prematurely activated, the input voltage must be applied before

a current source load is applied.
