The AZ1117E is a low-dropout three-terminal regulator with 1.0A
output current ability, and the dropout voltage is specified at typical
1.1V at 1.0A current load decreasing at lower load currents.
(Top View)
The AZ1117E is optimized for low voltage where transient response
and minimum input voltage are critical. It provides current limit and
thermal shutdown protection solutions. Its circuit includes a trimmed
band gap reference to assure output voltage accuracy to be within
±1%. On-chip thermal shutdown provides protection against a
combination of high current and ambient temperature that would
create excessive junction temperature.

The AZ1117E is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V
fixed-output voltage versions and ADJ output voltage version. The
fixed versions integrate the adjust resistors.
The AZ1117E is available in the industry-standard SOT-223 package.
