DESCRIPTION

KEY FEATURES

p GUARANTEED 0.4% INITIAL VOLTAGE

The LX1431 is an adjustable shunt voltage

regulator featuring 100mA sink capability, a

0.4% initial reference voltage tolerance and

a 0.3% typical temperature stability. This

product, which is ideal for use in Pentium^®

applications, is equipped with on-chip di-

vider resistors, enabling it to be configured

as a 5V shunt regulator. In this configura-

tion, the LX1431 has an initial voltage toler-

ance of only 1% and requires no additional

external components. The Linfinity

LX1431EB evaluation board and design kit

is available to assist engineers in quickly

configuring the most efficient, cost-effective

Pentium designs.

design of both adjustable and switching

power supplies. In addition, the nominal

internal current limit of 100mA may be de-

creased with the addition of a single exter-

nal resistor.

IMPEDANCE

p FAST TURN-ON

p SINK CURRENT CAPABILITY, 1mA TO 100mA

p LOW REFERENCE PIN CURRENT

For applications requiring an adjustable

reference, the Linfinity LX6431CLP, a simpli-

fied three-pin programmable reference, may

be used. Because the LX6431 is pin-for-pin

compatible with Linfinity's earlier TL431, use

of this product provides designers a simple

migration path to the more robust LX6431.

A separate LX6431 data sheet is available

which details the specifics of this product.

In addition, Pentium designers may use

Linfinity's LX8585/8585A 4.6A or LX8584/

8584A 7A Low Dropout Regulators to achieve

the most optimum motherboard configura-

tion.

The output voltage of the LX1431 may be

set to any value between 2.5V and 36V

through the addition of two external resis-
