PRODUCT DESCRIPTION

The AS2887 are low power 3A 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 AS2887 is designed for low voltage applications that offer 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 AS2887 features low dropout of a maximum of 1.5 volts.

The AS2887 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and

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

increases efficiency.

The AS2887 are offered in a 3-pin TO-220, TO-263 & TO-252 packages compatible with other 3 terminal regulators. For a 8A low

dropout regulator refer to the AS2880 data sheet.
