Description

The GL2148 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 “Worst” of operating conditions.

The GL2148 is stable with an output capacitance of 4.7 F or greater.
