AQ1117CY-M1-AJ-TRL Overview

low dropout 1 amp voltage regulator

AQ1117
Low Dropout
1 Amp Voltage Regulator
Product Specification
Revision 1.5
September 19, 2005
General Description
The AQ1117 is a low dropout three terminal
voltage regulator, offered in popular fixed options
or an adjustable version that can set a precise
voltage from 1.22V to 12V with two external
resistors.
AQ1117 is offered in SOT-89 which has a lower
thermal resistance and fits in smaller foot print
than a standard SOT-223.
With a dropout
voltage of less than one volt, the AQ1117 can be
used in applications where drop out voltage and
size are an issue.
To assure accuracy within 1.5% over
temperature the heart of the AQ1117 is a self-
correcting AcuRef™ bandgap reference.
On-chip current limit and thermal shutdown with
hysteresis protects against any combination of
overload and ambient temperature that might
cause the junction temperature to exceed safe
limits.
Applications
Graphic cards
PC motherboards
Switching power supply post-regulation
Telecom equipment
DVD video player
