AZ1117I
LOW DROPOUT LINEAR REGULATOR WITH INDUSTRIAL TEMPERATURE RANGE
Description
Pin Assignments
The DIODES™ AZ1117I is a low dropout three-terminal regulator
optimized for a low voltage where transient response and minimum
input voltage are critical. The device provides current-limit and
thermal-shutdown features. Its circuit includes a trimmed bandgap
reference to assure an output voltage accuracy of within ±1%. Onchip thermal shutdown provides protection against a combination of
high current and ambient temperature that may create excessive
junction temperature.

VOUT
The AZ1117I is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V
fixed output voltage versions and an 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.
