1A LOW-DROPOUT POSITIVE
FIXED AND ADJUSTABLE VOLTAGE REGULATOR
A1117
Description
The A1117 is designed to provide 1A for
requiring high efficiency applications. The
A1117 series of positive fixed voltage and
adjustable version, which can provide an output
voltage from 1.25V to 13.8V with only two
external resistors. The A1117 offers current
limiting and thermal protection to assure the
stability of chip and power system. And the on
chip trimming technique to guarantee output
voltage accuracy within ±1%.
The A1117 is available in SOT-223 and TO-252
package.
