General Descriptions
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 voltage is specified at 1.4V Maxi-
mum at full rated output current. The AME1117 series
provides excellent regulation over line, load and tem-
perature variations.
