DESCRIPTION

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.

TO-220

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 (V_IN-V_OUT≤3V).
