An Application of the LX8384A for the Pentium P54C Processors Meeting VRE Specification.
positive regulators designed to provide 5A
output current. These regulators yield
higher efficiency than currently available
devices with all internal circuitry designed
to operate down to a 1V input-to-output
differential. In each of these products, the
dropout voltage is fully specified as a
function of load current. Dropout is
guaranteed at a maximum of 1.3V (8384A)
and 1.5V (8384) at maximum output
current, decreasing at lower load currents.
reference voltage tolerance to 1% maximum
at room temperature and 2% maximum over
the 0 to 125°C range for the LX8384A,
making this ideal for the Pentium P54C-
VRE specification. The LX8384B offers
0.8% tolerance at room temperature and
1.0% maximum over line, load and
temperature.

capacitors. A minimum 10µF capacitor is
required on the input and a 15µF or greater

current flows into the load, thereby
increasing efficiency. This feature contrasts
with PNP regulators where up to 10% of the
output current is wasted as quiescent
current. The LX8384-xxI is specified over
