AQ120EX Datasheet, PDF (1/6 Pages) Acutechnology Semiconductor – LDO Regulator Controller SOT23-5 Package

Preliminary Specification
Revision 1.2
AQ120
LDO Regulator Controller
SOT23-5 Package
April 1, 2006
General Description
The AQ120 is a low cost LDO controller.
The AQ120 flexibility allows the setting of
the output voltage and controls up to 2
Amps of output current with a minimum
number of external components.
The open collector output is capable of
driving an external PNP transistor. A
temperature stable bandgap reference
(1.25 V) controls the output voltage and
is programmable through two external
resistors. The AQ120 if offered in the
very small SOT23-5 package.
Applications
• Graphic cards
