The LX8383/8383A/8383B series ICs are
positive regulators designed to provide
7.5A output current. All internal circuitry
is designed to operate down to a 1V in-
put-to-output differential, so the LX8383/
83A/83B can operate with greater effi-
ciency than previously available devices.
The dropout voltage for each product is
fully specified as a function of load cur-
rent.
Dropout is guaranteed at a maxi-
mum of 1.3V
for the LX8383A/83B and
1.5V
for the LX8383, at maximum output
current, decreasing at lower load currents.
Fixed versions are also available and speci-
fied in the Available Options table below.
The LX8383B offers a tighter voltage ref-
erence tolerance: 0.8% initial accuracy and
1% over line, load and temperature. The
LX8383/83A have 1% initial accuracy and
2% over line, load and temperature.
The LX8383/83A/83B series devices are
pin-compatible with earlier 3-terminal
regulators, such as the 117 series prod-
ucts. 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 LX8383/83A/83B 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 LX8383I/8383AI is
specified over the industrial temperature
range of -25°C to +125°C and the
LX8383C/8383AC/8383BC is specified
over the commercial range of 0°C to
+125°C.
