AZ1117E
1.0A LOW DROPOUT LINEAR REGULATOR
The AZ1117E has been optimized for low voltage where transient
response and minimum input voltage are critical. It provides current 3 INPUT
limit and thermal shutdown protection solutions. Its circuit includes a
trimmed band gap reference to assure output voltage accuracy to be
VOUT 2 OUTPUT
within ±1%. On-chip thermal shutdown provides protection against a
combination of high current and ambient temperature that would
create excessive junction temperature. 1 ADJ/GND
The AZ1117E is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V
fixed output voltage versions and ADJ output voltage version. The
fixed versions integrate the adjust resistors. Applications
The AZ1117E is available in the industry-standard SOT-223 package.

Note 2: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating
Conditions” is not implied. Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability.
