AZ1117BH-ADJTRE1

600mA LOW DROPOUT LINEAR REGULATOR 800mA LOW DROPOUT LINEAR REGULATOR 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 excessive junction temperature. The AZ1117B is available in 1.8V, 2.5V and 3.3V versions. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors. The AZ1117B is available in the industry-standard SOT-223 power package.
