www.DataSheet4U.com ISSUED DATE :2005/06/21 REVISED DATE : G5U2178 Description C M O S L o w D r o p o u t Vo l t a g e R e g u l a t o r The G5U2178 series of positive, linear regulators feature low quiescent current (45 A typ.) with low dropout voltage, making them 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. In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground. The G5U2178 is stable with an output capacitance of 4.7 F or greater.
