PRODUCT DESCRIPTION

The AS2850 are low power 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 AS2850 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 AS2850 features low dropout of a maximum 1.2 volts.

The AS2850 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and

increases efficiency.

The AS2850 are offered in a 3-pin TO-220 and TO-263 package compatible with other 3 terminal regulators. For a 8A low dropout

regulator refer to the AS2880 data sheet.
