AZ1117E
1.0A LOW DROPOUT LINEAR REGULATOR
Description
Pin Assignments
NEW PRODUCT
The AZ1117E is a low dropout three-terminal regulator with 1.0A
output current ability, and the dropout voltage is specified at typical
1.1V at 1.0A current load, decreasing at lower load currents.
(Top View)
The AZ1117E has been optimized for low voltage where transient
response and minimum input voltage are critical. It provides current
limit and thermal shutdown protection solutions. Its circuit includes a
trimmed band gap 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 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.

Typical Applications Circuit (Cont. Note 4)
Note 4:
The AZ1117E is compatible with Low ESR ceramic capacitor.
A minimum of 1.0μF input and output capacitors are required.
The ESR of the output capacitors must be less than 1.5Ω.
Close to the OUTPUT pin, it is not recommended to use a capacitor smaller than 0.68μF in parallel with output capacitor.
When the output capacitor parallels 0.1µF capacitor, the 0.1µF capacitor must be away from the OUTPUT pin, the distance is no less than 5mm.
