KEY FEATURES  
DESCRIPTION  
The LX1431 is an adjustable shunt voltage  
In addition, the nominal internal current limit of  
100mA may be decreased with the addition of a  
single external resistor.

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 divider resistors,  
enabling it to be configured as a 5V shunt  
regulator. In this configuration, the LX1431 has  
an initial voltage tolerance 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.  
„
For applications requiring an adjustable

„
reference, the Linfinity LX6431CLP,  
a
simplified 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 us
Linfinity's LX8585/8585A 4.6A or LX8584/  
8584A 7A Low Dropout Regulators to achieve  
the most optimum motherboard configuration.

The output voltage of the LX1431 may be set  
to any value between 2.5V and 36V through the  
addition of two external resistors, which is of  
particular importance in the design of both  
adjustable and switching power supplies.

Thick traces represent high current traces which  
must be low resistance / low inductance traces in  
order to achieve good transient response.
