Description
1 . 5 A C M O S L o w D ro p o u t Vo l t a g e R eg u l a t o r
The GE2138 series of positive, linear regulators feature low quiescent current (45 A 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 鈥淲orst鈥?of operating conditions.
The GE2138 is stable with an output capacitance of 4.7 F or greater.
