These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the “Worst” of operating conditions. As an additional feature, the GQ2181 is stable with an output capacitance of just extended 0.22 F or greater. Features Applications Very Low Dropout Voltage Guaranteed 150mA output Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Excellent PSRR Type 70dB Noise Reduction Bypass Capacitor Power-saving Shutdown Mode Factor Pre-set Output Voltage Functional Block Diagram Package Dimensions Battery Powered Widgets Instrumentation Wireless Devices PC Peripherals Portable Electronics Cordless Phones Electronic Scales Cellular Phones Cameras Telecommunications REF.
