n General Description

The AME1117 is a 1A low-dropout positive voltage regu-

lator. It is available in fixed and adjustable output voltage

versions. Overcurrent and thermal protection are integrated

onto the chip. Output current will limit as while it reaches

the pre-set current or temperature limit. The dropout volt-

age is specified at 1.4V Maximum at full rated output

current. The AME1117 series provides excellent regula-

tion over line, load and temperature variations.
