EC50117S-1A Low Dropout Positive Voltage Regulator

General description

The EC50117S series of positive adjustable and fixed  regulators are designed to provide 1A with high efficiency. All internal circuitry is designed to operate down to 1.4V input to output differential. On-chip trimming adjusts the reference voltage to 1%. Current limit the typical value of 1.5A allows to minimizing the stress on both the regulator and the power source circuitry under overload conditions.
