General Description
The AZ1117B is a low dropout three-terminal regulator 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 shutdown. 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 excessivejunction temperature.
