DESCRIPTION

The SPX2940 is a 1A, accurate voltage regulators with a low drop out voltage of 280mV (typical)

at 1A. These regulators are specifically designed for low voltage applications that require a low

dropoutvoltageandafasttransientresponse. Theyarefullyfaultprotectedagainstover-current,

reverse battery, and positive and negative voltage transients.

The SPX2940 is offered in 3-pin TO-220 & TO-263 packages. For a 3A version, refer to the

SPX29300 data sheet.
