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 Block Diagram & 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% & ß ‡Temperature Coefficient
