AZ1117I
LOW DROPOUT LINEAR REGULATOR WITH INDUSTRIAL TEMPERATURE RANGE
Description
Pin Assignments
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.
VOUT
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.
