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.

voltage to 1% (0.8% for the 8386B) initial

accuracy and 2% (1% for the 8386B) over

line, load, and temperature.

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.

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°C to

+125°C and the LX8386/86A/86B is

specified over the commercial range of 0°C

to 125°C.
