G5U2187

ISSUED DATE :2006/04/12 REVISED DATE : G5U2187 Description 7 5 0 m A C M O S P o s i t i v e Vo l t a g e R e g u l a t o r The G5U2187 of positive, linear regulators feature low quiescent current (45 A typ.) with low dropout voltage, making then ideal for battery applications. Output voltages are set at the factory and trimmed to 1.5% accuracy. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the “Worst” of operating conditions. The G5U2187 is stable with an output capacitance of 4.7 F or greater.
