DESCRIPTION
The LX8386/86A/86B series ICs are
positive regulators designed to provide
1.5A 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 this
product, the dropout voltage is fully
specified as a function of load current.
Dropout is guaranteed at a maximum of
1.3V (LX8386A/86B) and 1.5V (LX8386)
at maximum output current, decreasing
at lower load currents. On-chip
trimming adjusts the reference voltage
to 1% (0.8% for the 8386B) initial
accuracy and 2% (1% for the 8386B)
over line, load and temperature.
The LX8386/86A/86B series devices
are pin-compatible with earlier 3-
terminal regulators, such as 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 LX8386/86A/86B series quiescent
current flows into the load, increasing
efficiency. This feature contrasts with
PNP regulators, where up to 10% of the
output current is wasted as quiescent
current. The LX8386-xxI is specified
over the full industrial temperature
range of -25掳C to +125掳C and the
LX8386/86A/86B-xxC is specified over
the commercial range of 0掳C to +125掳C.
