DESCRIPTION

KEY FEATURES

■ THREE-TERMINAL ADJUSTABLE OR FIXED

The LX8384/84A/84B Series ICs are posi-

tive regulators designed to provide 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

(8384A) and 1.5V (8384) at maximum

output current, decreasing at lower load

currents.

In addition, on-chip trimming adjusts

the reference voltage tolerance to 1%

maximum at room temperature and 2%

maximum over the 0 to 125°C range

for the LX8384A, making this ideal for

the Pentium P54C-VRE specification.

The LX8384B offers 0.8% tolerance at

room temperature and 1.0% maximum

over line, load and temperature.

Fixed versions are also available and

specified in the Available Options table

below.

The LX8384/84A/84B Series devices

are pin-compatible with earlier 3-

terminalregulators, 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 LX8384/84A/84B Series quiescent

current flows into the load, thereby

increasing efficiency. This feature

constrasts with PNP regulators where up

to 10% of the output current is wasted as

quiescent current. The LX8384-xxI is

specified over the industrial temperature

range of -25°C to 125°C, while the

LX8384-xxC/84A-xxC/84B-xxC is

specified over the commercial range of

0°C to 125°C.
