ZENER SHUNT REGULATOR
ISSUE 3 DECEMBER 1997
DEVICE DESCRIPTION
The ZR2431 is a three terminal adjustable
shunt regulator offering excellent
temperature stability and output current
handling capability up to 25mA. The output
voltage may be set to any chosen voltage
between 1.24 and 15 volts by selection of
two external divider resistors.
The devices can be used as a replacement
for zener diodes in many applications
requiring an improvement in zener
performance.
The ZR2431 is particularly used in the
feedback control loop of switch mode power
supplies. In this application the device 1.24
volt reference enables the generation of low
voltage supplies, typically 3.3 volts or 3 volts.

Deviation of reference input voltage, Vdev, is defined as the maximum variation of the
reference input voltage over the full temperature range.
Vmax
The average temperature coefficient of the
reference input voltage, Vref is defined as:
Vref

When the device is programmed with two
external resistors, R1 and R2, (fig 2) , the
dynamic output impedance of the overall
circuit, R’, is defined as:
R=Rz (1+RR12)
† With a capacitance of greater than 100pF
between cathode and anode, minimum
cathode current must be 0.2mA.
