AQ533
Ultra-Low Dropout
500mA Voltage Regulator
Product Specification
Revision 1.7
September 13, 2006
General Description
The AQ533 is an ultra-low dropout voltage
regulator capable of delivering
500 mA
to the
load. It is adjustable and can set a precise
voltage from 1.22V to 12V with two external
resistors. The AQ533 meets all specifications
down to 1.22V output, unlike CMOS LDO’s which
loose performance with outputs below 2.25V.
The
enable
pin provides a remote turn-off for low
power consumption. It draws virtually zero current
in shutdown mode and implements Sequential,
Ratiometric,
or
Simultaneous
sequencing
schemes. This also allows for a separate bias
connection from the pass transistor in order to
achieve
ultra low dropout
from V
IN
to V
OUT
.
Reverse current protection
blocks current
flowing from V
OUT
to V
IN
when the AQ533 is
disabled. No current flows.
To assure accuracy within
1.5% over
temperature,
the heart of the AQ533 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.

Graphic cards
PC motherboards
