SPX1580 7A Ultra Dropout Voltage Regulator
Copyright 2004 Sipex Corporation
The SPX1580 is designed as a high performance
and low cost solution for application requiring a
lower dropout than traditional NPN regulators.
The SPX1580 uses a separate input voltage V
CTRL
( V
CTRL
≥
V
OUT
+ 1.3V) to minimize the dropout
voltage. This allows the 2.5V power for the load
to come from a 3.3V system supply.
As added benefit this will reduce the heat dissi-
pation*, and lower heatsink and cooling fan cost.
A typical application would use 3.3V for V
IN
and 5.0V for V
CTRL
from a motherboard power
supply to provide a nominal 2.5V output. Using
the sense pin allows Kelvin measure the output,
reducing resistance-associated errors.
The SPX1580 can power the 2.5V core voltage
for microprocessors such as a PentiumPC
TM
,
P55C
TM
, AMD5k86
TM
and K6
TM
and the IBM
PowerPC
TM
603EV and 604EV processors.
