Description
The GE2138 series of positive, linear regulators feature low quiescent current (45ꢀA 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 GE2138 is stable with an output capacitance of 4.7ꢀF or greater.
