GM1117
1A LOW DROPOUT PRECISION VOLTAGE REGULATOR
Features Description
The GM1117 is a positive low dropout regulator and is available in an adjustable version and fixed output voltage from 1.5V to 5.0V. All internal circuitry is designed to operate down to 800mV input to output differential and the dropout voltage is fully specified as a function of load current. On chip trimming adjusts the reference/output voltage to within 1%. Current limit is also trimmed in order to minimize the stress on both the regulator and the power source circuitry under overloaded conditions. Adjustable or Fixed Output Output Current of 1.0A Dropout Voltage 1.5V max @ 1.0A Line Regulation 0.2% max. Load Regulation 0.4% max. Fast Transient Response Current Limit Protection Thermal Shutdown Protection
