ADJUSTABLE PRECISION  
ZENER SHUNT REGULATOR  
Issue 2 - February 1998  
ZH431  
DEVICE DESCRIPTION  
FEATURES  
The ZH431 is a three terminal adjustable  
shunt regulator offering excellent  
temperature stability and output current  
handling capability up to 30mA. The output  
voltage may be set to any chosen voltage  
between 2.5 and 36 volts by selection of two  
external divider resistors.  
Surface mount SO8, SOT223,SOT23  
and SOT89 packages  
TO92 package  
2% and 1% tolerance  
Maximum temperature coefficient 55  
ppm/°C  
Temperature compensated for  
operation over the full temperature  
range  
The devices can be used as a replacement  
for zener diodes in many applications  
requiring an improvement in zener  
performance.They are also ideal for use in  
the feedback circuits of off line SMPUs as  
well as many general purpose regulator and  
reference applications where initialaccuracy  
and low temperature coefficient are key  
requirements.  
Programmable output voltage  
50µA to 30mA current sink capability  
Low output noise  
APPLICATIONS  
Shunt regulator  
Note:  
Series regulator  
ZH431 is not recommended for new designs.
