LM2940 - 1A Low Dropout Regulator

Download the LM2940 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same 1a low dropout regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2940/LM2940C positive voltage regulator

Key Features

  • the ability to source 1A of output current with a dropout voltage of typically 0.5V and a maximum of 1V over the entire temperature range. Furthermore, a quiescent current reduction circuit has been included which reduces the ground current when the differential between the input voltage and the output voltage exceeds approximately 3V. The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 30 mA. Higher quiescent currents only exist when the regu.

LM2940/LM2940C 1A Low Dropout Regulator March 2000 LM2940/LM2940C 1A Low Dropout Regulator General Description The LM2940/LM2940C positive voltage regulator features the ability to source 1A of output current with a dropout voltage of typically 0.5V and a maximum of 1V over the entire temperature range. Furthermore, a quiescent current reduction circuit has been included which reduces the ground current when the differential between the input voltage and the output voltage exceeds approximately 3V. The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 30 mA. Higher quiescent currents only exist when the regulator is in the dropout mode (VIN − VOUT ≤ 3V).
