ISSUED DATE :2004/09/22 REVISED DATE : G M 2 11 4 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 Description The GM2114 series of positive, linear regulators feature low quiescent current (30uA 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 GM2114 is stable with an output capacitance of 2.2uF or greater. Features Very Low Dropout Voltage Guaranteed 350mA output Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Factory Pre-set Output Voltage Highly Accurate± 2% Temperature Coefficient Block Diagram Applications Battery Powered Widgets Instrumentation Wireless Devices Cordless Phones PC Peripherals Portable Electronics Electronic Scales Package Dimensions SOT-89 REF.
