PRODUCT DESCRIPTION

The AS2830 is a low power 3A adjustable and fixed voltage regulator that is very easy to use. It requires only 2 external resistors to

set the output voltage for adjustable version. The AS2830 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 AS2830 features low dropout of a maximum 1.2 volts.

The AS2830 offers over current limit and full protection against reversed input polarity, reversed load insertion, and positive and

increases efficiency.

The AS2830 are offered in a 3-pin TO-220, TO-263 & TO-252 packages compatible with other 3 terminal regulators. For a 5A low

dropout regulator refer to the AS2850 data sheet.
