These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the “Worst” of operating conditions. An additional feature is a “Power Good” detector, which pulls low when the output is out of regulation. The GQ2133 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 Highly Accurate± 1.5% Power Good Output Function Power-saving Shutdown Mode Factor Pre-set Output Voltage Functional Block Diagram Battery Powered Widgets Instrumentation Wireless Devices PC Peripherals Portable Electronics Cordless Phones Electronic Scales Note: If output voltage specification is lower than 1.215V, Vref will be trimmed to 1.2V Package Dimensions REF.
