1A CURRENT LIMIT AND THERMAL PROTECTION

DESCRIPTION

FEATURES

A1117A is a series of low dropout three-terminal

regulators with a typical dropout of 1.3V at 1A load

current.

⚫

Maximum output current is 1A

Range of operation input voltage: Max 15V

Line regulation: 0.1%/V (typ.)

Load regulation: 10mV (typ.)

Besides fixed voltage version (V_OUT= 1.2V, 1.8V,

2.5V, 3.3V, 5V), A1117A has an adjustable version

that can provide an output voltage from 1.25 to 12V

with two external resistors.

Environment Temperature: -20°C ~85°C

Available in SOT-223 , TO-252 and SOT89-3

packages

APPLICATION

A1117A offers thermal shut down functions to assure

stability of chip and power system. Trimming

technique is used to guarantee output voltage

accuracy within ±2%.
