3A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR

THERMAL SHUTDOWN AND CURRENT LIMIT FUNCTIONS

DESCRIPTION

FEATURES

ꢀ

Provide Fixed Version and an Adjustable

Version, Output Value can be customized on

command.

The A1085 is a series of low dropout three terminal

regulators with a dropout of 1.3V at 3A load current.

Other than a fixed version (V_OUT=1.8V, 2.5V, 3.3V,

5V), The A1085 has an adjustable version, which

can set the output voltage with only two external

resistors.

ꢀ

Maximum Output Current: 3A

Output Voltage Accuracy within ±2%

Range of Operation Input Voltage: Max 15V

Line Regulation: 0.2% (Typ.)

Load Regulation: 0.4% (Typ.)

Environment Temperature: -50^oC~+140^oC

The A1085 offers thermal shut down and current

limit functions, to assure the stability of chip and

power system. And the A1085 uses trimming

technique to guarantee output voltage accuracy

within ±2%

Available in TO-252, TO-263-2 and TO-263-3
