ISSUED DATE :2004/11/05 REVISED DATE : GL2146 C M O S P o s i t i v e Vo l t a g e R eg u l a t o r Description The GL2146 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 GL2146 is stable with an output capacitance of 2.2 F or greater.
