H E

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.

specified in the Available Options table

below. The LX8382/82A have 1%

initial voltage reference accuracy and

products. While a 10µF output

regulator designs.

increasing efficiency. This feature

contrasts with PNP regulators, where

up to 10% of the output current is

wasted as quiescent current. The

commercial range of 0°C to +125°C.
