description

The SPX2815 is a low power 1.5A that is available in either an

adjustable or fixed output voltage version. It requires only 2 external

resistors to set the output voltage for the adjustable version. This

device is an excellent choice for use in powering low voltage micro-

processor that require a lower dropout voltages and faster transient or

as a post regulator for switching supply applications. The SPX2815

has a very low quiescent current and a low dropout voltage of 1.2V at

full load. The SPX2815 features over current limit and protection

against over-current faults, reversed input polarity, reversed load inser-

tion, and positive and negative voltage transients.

The SPX2815 is offered in industry standard 3-pin TO-220, TO-263

and TO-252 packages.
