General Description

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 protecti on against

a combination of high current and ambient temperature

that would create excessive junction temperature.

The AZ1117B is availa ble in 1.8V, 2.5V and 3.3V ver-

sions. 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.
