LOW DROPOUT LINEAR REGULATOR
Description
The AZ1117C is a low dropout three-terminal regulator.
The AZ1117C 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 AZ1117C 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 AZ1117C is available in the industry-standard TO252-2 Series
(including TO252-2 (3), TO252-2 (4), and TO252-2 (5)), SOT89 and
SOT223 power packages.
