LM2940 - 1A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR

General 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.

Key Features

  • 500mV Typically Dropout at 1A.
  • Output Current in Excess of 1A.
  • Low Quiescent Current.
  • Reversed-Battery Protection.
  • Current Limit and Thermal Shutdown.
  • Mirror Image Insertion Protection.

UNISONIC TECHNOLOGIES CO., LTD LM2940 LINEAR INTEGRATED CIRCUIT 1A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR 1  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. 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-VOUT≤3V).  FEATURES * 500mV Typically Dropout at 1A * Output Current in Excess of 1A * Low Quiescent Current * Reversed-Battery Protection * Current Limit and Thermal Shutdown.
