The LX8384/84A/84B Series ICs are

positive 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

The LX8384/84A/84B Series devices are

pin-compatible with earlier 3-terminal

regulators, such as the 117 series products,

but they do require input and output

capacitors. A minimum 10µF capacitor is

required on the input and a 15µF or greater

on the output of these new devices for

stability. Although, these capacitors are

generally included in most regulator

designs.

The LX8384/84A/84B 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 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.
