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 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 (8386A/
86B) and 1.5V (8386) 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 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 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 鈥?5擄C to
+125擄C and the LX8386/86A/86B is
specified over the commercial range of 0擄C
to 125擄C.
