The GJ2137 series of positive, linear regulators feature low quiescent current (30 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 GJ2137 is stable with an output capacitance of 2.2 F or greater.
Features
