Regulator
features
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.
