A1117A BIPOLAR LDO REGULATOR 1A CURRENT LIMIT AND THERMAL PROTECTION

2020-04-26
A1117A is a series of low dropout three-terminal

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

current.

Besides fixed voltage version (VOUT = 1.2V, 1.5, 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.

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%.

The A1117A is available in SOT-223, TO-252 and

SOT89-3 Packages.
