DESCRIPTION

KEY FEATURES

■ Three-Terminal Adjustable Or Fixed

TheLX8385/85A/85Bseriesdevicesare

pin-compatible with earlier 3-terminal

The LX8385/8385A/8385B series ICs are

positive regulators designed to provide

3A output current. Each regulator yields

higher efficiency than currently available

devices with all internal circuitry designed

to operate down to a 1V input-to-output-

differential. In these products, the drop-

out voltage is fully specified as a function

of load current. The LX8385's dropout is

guaranteed at a maximum of 1.5V at maxi-

mum output current, decreasing at lower

load currents. The LX8385A/85B have a

maximum dropout voltage of 1.3V.

Output Voltage

■ Guaranteed 1% Voltage Reference

Accuracy Over Line, Load And

Temperature (LX8385B)

regulators, such as 117 series products.

While a 10µF output capacitor is required

on both input and output of these new

devices, this is generally included in most

regulator designs.

The quiescent current of the LX8385/

85A/85B series products flows into the

load, increasing efficiency. This feature

contrasts with PNP regulator designs,

where up to 10% of the output current is

wasted as quiescent current.

■ Guaranteed < 1.5V Headroom At 3A

(LX8385)

■ Guaranteed < 1.3V Headroom At 3A

(LX8385A/8385B)

■ Output Current Of 3A Minimum

p 0.015% Line Regulation

p 0.1% Load Regulation

The LX8385B offers a tighter voltage

reference tolerance: ±1.0% over line, load

and temperature, with 0.8% initial accu-

racy. The LX8385/85A have 1.0% initial

accuracy, with 2% over line, load and tem-

perature.

The LX8385-xxI is rated for -25°C to

+125°Capplications, andtheLX8385-xxC

/8385B-xxC is rated for 0°C to +125°C

applications.
