AZ1117I

LOW DROPOUT LINEAR REGULATOR WITH INDUSTRIAL TEMPERATURE RANGE

Description

The AZ1117I is available in industrial temperature range low dropout

three-terminal regulator.

The AZ1117I is 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 AZ1117I is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed

output voltage versions and ADJ output voltage version. 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 AZ1117I is available in the industry-standard SOT223 and

TO252-2 power packages.
