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
negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The I
Q
of this device flows into the load, which
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.
