DESCRIPTION

KEY FEATURES

■ THREE-TERMINAL ADJUSTABLE OR FIXED

The LX8382/8382A series ICs are

positive regulators designed to provide

10A output current. All internal

2% over line, load and temperature.

The LX8382/82A series devices are

OUTPUT VOLTAGE

■ GUARANTEED < 1.4V HEADROOM AT 10A

pin-compatible with earlier 3-terminal

regulators, such as the 117 series

products. 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 LX8382/82A 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

LX8382/82A-xxC is specified over the

commercial range of 0°C to +125°C.

(LX8382)

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.

Fixed versions are also available and

specified in the Available Options table

below. The LX8382/82A have 1%

initial voltage reference accuracy and
