The LX8384/84A/84B Series ICs are posi-
tive 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.
In addition, on-chip trimming adjusts
the 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.
Fixed versions are also available and
specified in the Available Options table
below.
The LX8384/84A/84B Series devices
are pin-compatible with earlier 3-
terminal regulators, such as the 117 series
products. While a 10μF output capacitor
is required on both input and output of
these new devices, this capacitor is
generally included in most regulator
designs.
The LX8384/84A/84B Series quiescent
current flows into the load, thereby
increasing efficiency. This feature
constrasts with PNP regulators where up
to 10% of the output current is wasted as
quiescent current. The LX8384-xxI is
specified over the industrial temperature
range of -25°C to 125°C, while the
LX8384-xxC/84A-xxC/84B-xxC is
specified over the commercial range of
0°C to 125°C.
