The LX8384/84A/84B Series ICs are
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.
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,
but they do require input and output
capacitors. A minimum 10μF capacitor is
required on the input and a 15μF or greater
on the output of these new devices for
stability. Although, these capacitors are
generally included in most regulator
designs.
The LX8384/84A/84B Series quiescent
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
the industrial temperature range of -25°C to
125°C,
while
the
xxC/84B-xxC
is
specified
commercial range of 0°C to 125°C.
