Description

The SPX1585AT-L-33 is a low power 5A adjustable and fixed voltage regulator that is very easy to use. It requires only 2 external resistors to set the output voltage for the adjustable version. This device is designed for low voltage applications that offer lower dropout voltage and faster transient response. It is an excellent choice for use in powering low voltage microprocessors 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 SPX1585AT-L-33 features low dropout of a maximum 1.2 volts.
