PRODUCT DESCRIPTION
The AS2715 is a 1.5A high accuracy, low dropout voltage regulator with only 350mV(Typ.)@ 1.5A). The AS2715 is designed for
low voltage application that requires 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 AS2715 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%. Features such as Enable pin, Error Flag pin are
also included in the 5 pin packages.
The AS2715 is offered in a 3 & 5-pin TO-220 & TO-263 package compatible with other 3 terminal regulators. For a 3A low dropout
regulator refer to the AS2730 data sheet.
