DEVICE DESCRIPTION
The ZR431L is a three terminal adjustable
s h u n t r e g u l a t o r o f f e r i n g e x c e l l e nt
temperature stability and output current
handling capability up to 25mA. The output
voltage may be set to any chosen voltage
between 1.24 and 10 volts by selection of
two external divider resistors.
The devices can be used as a replacement
for zener diodes in many applications
r e q u i r i n g a n i m p r ov e me nt i n z e n e r
performance.
The ZR431L 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.
