PRODUCT DESCRIPTION
The AS2815 is a low power 1.5A 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 AS2815 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 AS2815 features low dropout of a maximum 1.2V.
The AS2815 offers over current limit and protection against over-current faults, reversed input polarity, reversed load insertion, and
positive and negative transient voltage. The I
Q
of this device flows into the load, which increases efficiency.
The AS2815 are offered in a 3-pin TO-220, TO-263 & TO-252 packages compatible with other 3 terminal regulators. For a 3A low
dropout regulator refer to the AS2830 data sheet.
