The AMS1117-ADJ and AMS1117-1.2,-1.5,-1.8,-1.9,-2.5

-3.3 and-5.0 are low dropout three-terminal regulators with

0.8A output current capability.These devices have been

optimized for low voltage where transient response and

minimum input voltage are critical.

On-chip thermal limiting provides protection against any

combination of overload and ambient temperatures that

would create excessive junction temperatures.

The AMS1117 series regulators are available in the indus-

try-standard SOT-89 packages.
