BL2940 - 1A Low-Dropout Regulator

Description

The BL2940 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 SOT223 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 TO-252 current and an input-output differential of 5V is therefore only 30 mA. Higher quiescent currents on.

BL2940 1A Low-Dropout Regulator BL2940 DESCRIPTION The BL2940 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 SOT223 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 TO-252 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).
