1A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR

The UTC LM2940 is a low dropout Regulator designed to provide output current up to 1A with a typically 500mV dropout Voltage and a maximum of 1V. It is capable of reducing the ground current when the differential between the input voltage and the output voltage outrun 3V. UTC LM2940 offers low quiescent current (typically 30mA at 1A and an input-output differential of 5V). Higher quiescent currents only exist when the Regulator is in the dropout mode (VIN-VOUT3V).
