DESCRIPTION

KEY FEATURES

■ THREE-TERMINAL ADJUSTABLE OR FIXED

The LX8383/8383A/8383B series ICs are

positive regulators designed to provide

7.5A output current. All internal circuitry

is designed to operate down to a 1V in-

put-to-output differential, so the LX8383/

83A/83B can operate with greater effi-

ciency than previously available devices.

The dropout voltage for each product is

fully specified as a function of load cur-

rent. Dropout is guaranteed at a maxi-

mum of 1.3V for the LX8383A/83B and

1.5V for the LX8383, at maximum output

current, decreasing at lower load currents.

Fixed versions are also available and speci-

fied in the Available Options table below.

The LX8383B offers a tighter voltage ref-

erence tolerance: 0.8% initial accuracy and

1% over line, load and temperature. The

LX8383/83A have 1% initial accuracy and

2% over line, load and temperature.

pin-compatible with earlier 3-terminal

regulators, such as the 117 series prod-

ucts. 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 LX8383/83A/83B 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 LX8383I/8383AI is

specified over the industrial temperature

range of -25°C to +125°C and the

LX8383C/8383AC/8383BC is specified

over the commercial range of 0°C to

+125°C.
