UNISONIC TECHNOLOGIES CO.,LTD LM2940 LINEAR INTEGRATED CIRCUIT 1A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR 1 1 TO-263 TO-263-3 DESCRIPTION The UTC LM2940 is a low dropout regulator designed to provide 1 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 TO-220 the differential between the input voltage and the output voltage outrun 3V. UTC LM2940 offers low quiescent current (typically 30mA at 1A 1 1 and an input-output differential of 5V). Higher quiescent currents only exist when the regulator is in the dropout mode (VIN-VOUT≤3V).
