These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the “Worst” of operating conditions. The GM2123 is stable with an output capacitance of 2.2 F or greater. Features Applications Very Low Dropout Voltage Guaranteed 300mA output Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Factory Pre-set Output Voltage Highly Accurate± 1.5% Temperature Coefficient Block Diagram Package Dimensions Battery Powered Widgets Instrumentation Wireless Devices Cordless Phones PC Peripherals Portable Electronics Electronic Scales SOT-89 REF.
