AZ1117B
The AZ1117B is a low dropout three-terminal regula-
tor with a dropout of 1.2V at 800mA output current.
The AZ1117B has been optimized for low voltage
where transient response and minimum input voltage
are critical. It provides current limit and thermal shut-
down. Its circuit includes a trimmed bandgap 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.
