CS52333
500 mA and 1.5 A, 3.3 V
Dual Input Linear Regulator
with Auxiliary Control
The CS52333 provides a glitchfree 3.3 V output from one of three
possible supplies, (V
IN
, V
SB
and 3.3 V
AUX
). An onchip linear
regulator powers the output when either V
IN
or V
SB
is available.
Otherwise AuxDrv turns on an external PFET, which connects the
3.3 V
AUX
supply to the output. The CS52333 is intended to provide
power to an ASIC on a PCI Network Interface Card (NIC), and meets
Intel’s “Instantly Available” power requirements which follow from
the Advanced Configuration and Power Interface (ACPI) standards.
Other applications include desktop computers, power supplies with
multiple input sources, and PCMCIA interface cards.
The CS52333 linear regulator provides a fixed 3.3 V output at up
to 1.5 A with an overall accuracy of
±
2%. The internal NPN PNP
composite pass transistor provides a low dropout voltage and requires
less supply current than a straight PNP design. Full protection with
both current limit and thermal shutdown is provided. Designed for low
reverse current, the IC prevents excessive current from flowing from
V
OUT
to either V
IN
or ground when the regulator input voltage is
lower than the output. The auxiliary drive control feature allows the
use of an external PFET to supply power to the output when the
regulator supplies are off.
The CS52333 regulator is available in two package types: the 5
Lead D
2
PAK package (TO263) and SOIC8 with 4 Lead Fused
(DF8) package. When powered from the V
IN
source, the D
2
PAK5 is
rated for 1.5 A and the SOIC8 is rated for 500 mA. Both packages are
rated for 500 mA when only powered from the V
SB
source.
