PRODUCT DESCRIPTION
The SPX2815 is a low power 1.5A adjustable and fixed voltage regulators that are very easy to use. It requires only 2 external
resistors to set the output voltage for adjustable version. The SPX2815 are designed for low voltage applications that offers lower
dropout voltage and faster transient response. This device is an excellent choice for use in powering low voltage microprocessor that
require a lower dropout, faster transient response to regulate from +2.5V to 3.8V supplies and as a post regulator for switching
supplies applications. The SPX2815 features low dropout of a maximum 1.2V.
The SPX2815 offers over current limit and protection against over-current faults, reversed input polarity, reversed load insertion, and
positive and negative transient voltage. The IQ of this device flows into the load, which increases efficiency.
The SPX2815 are offered in a 3-pin TO-220, TO-263 & TO-252 packages compatible with other 3 terminal regulators. For a 3A low
dropout regulator refer to the SPX1587 data sheet.
