DESCRIPTION
The LX8382/8382A series ICs are
positive regulators designed to provide
10A output current. All internal
circuitry is designed to operate down
to a 1V input-to-output differential, so
the LX8382/82A can operate with
greater efficiency than previously
available devices. The dropout voltage
for each product is fully specified as a
function of load current.
Dropout is
guaranteed at a maximum of 1.4V
for the LX8382 and 1.2V for the
LX8382A at maximum output current,
decreasing at lower load currents.
Fixed versions are also available and
specified in the Available Options table
below. The LX8382/82A have 1%
initial voltage reference accuracy and
2% over line, load and temperature.
The LX8382/82A series devices are
pin-compatible with earlier 3-terminal
regulators, such as the 117 series
products. While a 10碌F output
capacitor is required on both input and
output of these new devices, this
capacitor is generally included in most
regulator designs.
The LX8382/82A 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
LX8382/82A-xxC is specified over the
commercial range of 0掳C to +125掳C.
