SPX3940 Datasheet 1a Low Dropout Voltage Regulator

Manufacturer: MaxLinear

Overview: July 3, 2023 GENERAL.

General Description

The SPX3940 is a 1A, accurate voltage regulator with a low drop out voltage of 280mV (typical) at 1A.

These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response.

They are fully fault protected against overcurrent, reverse battery, and positive and negative voltage transients.
