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 1.45V Maximum at full rated output
current. The AME1117 series provides excellent regula-
tion over line, load and temperature variations.
