AS2830AT-1-5/TR

The AS2830AT-1-5/TR is a low power 3A adjustable and fixed voltage regulator that is very convenient to use. It demands only 2 external resistors to set the output voltage for adjustable version. The  AS2830AT-1-5/TR is desi gned for low voltage applications that provides lower dropout voltage and faster transient response. This device is an ideal choice for use in powering low voltage microprocessor that require a lower dropout, faster transient resp onse to regulate from +2.5V to 3.8V supplies and as a post regulator for switching supplies applications. The AS2830 AT-1-5/TR features low dropout of a maximum 1.2 volts.

Features of the AS2830AT-1-5/TR are:(1)adjustable output down to 1.2V;(2)fixed output voltages is 1.5V, 2.5V, 3.3V and 5.0V ;(3)output current of 3A;(4)low dropout voltage 1.1V typ;(5)extremely tight load and line regulation ;(6)cur rent and thermal limiting;(7)standard 3-terminal low cost TO-220, TO-263 and TO-252;(8)similar to industry standard LT1085/LT1585.
