SPX3940AM3-L-3-3/TR

低压差稳压器 1.0A LW DROPOUT VLT 1.5A PEAK OUTPT CURR

GENERAL DESCRIPTION SPX3940AM3-L-3-3/TR

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.

The SPX3940 is offered in 3-pin SOT223 and

TO-263 packages. For a 3A version, refer to

the SPX29300 data sheet.
