SPX1582 3A Ultra Low Dropout Voltage Regulator
©Copyright 2004 Sipex Corporation
The SPX1582 is designed as a high performance
and low cost solution for application requiring a
lower dropout than traditional NPN regulators.
The SPX1582 uses a separate input voltage VCTRL
( VCTRL ≥ VOUT + 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 VIN
and 5.0V for VCTRL 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 SPX1582 can power the 2.5V core voltage
for microprocessors such as a PentiumPCTM,
P55CTM, AMD5k86TM and K6TM and the IBM
PowerPCTM 603EV and 604EV processors.

DESCRIPTION
1
SENSE
Allows Kelvin sense of VOUT at the load. (Positive side of the
reference voltage of the device).
2
ADJ
Negative side of the reference voltage for the device. Adding a small
bypass capacitor from the ADJ pin to ground will improve the transient
response.
3VOUT
Power output of the device.
4VCTRL
Supply pin for the control circuitry of the device. The current flow into this
pin will be about 1% of the output current. VCTRL must be between 1.0V
and 1.3V greater than the output voltage for the
device to regulate.
5VIN
Output load current is supplied through this pin. VIN must be between 0.1V
and 0.8V greater than the output voltage for this device to regulate.
