ZLDO1117Q
AUTOMOTIVE COMPLIANT 1A LOW DROPOUT POSITIVE REGULATOR
WITH FIXED AND ADJUSTABLE OUTPUTS
Description
Pin Assignments
The ZLDO1117Q is a low dropout positive adjustable or fixed-mode
regulator with 1A output current capability.
(Top View)
The ZLDO1117Q has
a 2% tolerance across the industrial
VIN
temperature range and is guaranteed to have lower than 1.2V dropout
at full load current making it ideal to provide well-regulated outputs of
1.2V to 5.0V with input supply voltages up to 18V.
VOUT
ADJ/GND
The ZLDO1117Q is ideally suited to provide well-regulated supplies
for low voltage IC applications such as high-speed bus termination
and low current 3.3V logic supply across the whole industrial
temperature range.
