KEY FEATURES

DESCRIPTION

The LX6431 series precision adjustable three

terminal shunt voltage regulators are pin-to-pin

compatible with the industry standard TL431, but

equipment as well as reducing the voltage

programming errors due to the impedance of the

divider network (See product Highlight)

Unconditionally Stable for All

Cathode To Anode Capacitance

Values

with significant improvements.

The LX6431

In addition, the LX6431B has an improved

initial accuracy of 0.4%, and the output voltage is

programmable by using two external resistors

from 2.5V to 36V.

These devices offer low output impedance for

improved load regulation. The typical output

impedance of these devices is 100mΩ. The

reduced reference input bias current and minimum

operating currents make these devices suitable for

portable and micro power applications.

Sink Current Capability 0.6mA to

Impedance Less Than 100mΩ

Adjustable Output Voltage From

2.5V to 36V

design has eliminated regions of instability

common to older generation shunt regulator

products like the TL431. Designs are made simpler

by eliminating the task of insuring capacitive loads,

and output voltage and cathode currents don’t

combine for unstable operation. The capacitor

value is chose simply to give the best load transient

response without the possibility of instability.

lower reference input current allows the use of

higher value reference divider resistors, reducing

the current drain from batteries in portable
