ZR431
ADJUSTABLE PRECISION ZENER SHUNT REGULATOR
Description
The ZR431 is a three terminal adjustable shunt regulator
offering excellent temperature stability and output current
handling capability up to 100mA. The output voltage may be
set to any chosen voltage between 2.5 and 20 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.
Features
• Surface mount SOT223 and SOT23 packages
• 2%, 1 % and 0.5% tolerance
• Max. temperature coefficient 55 ppm/°C
• Temperature compensated for operation
• over the full temperature range
• Programmable output voltage
• 50μA to 100mA current sink capability
• Low output noise
• All package options available in “Green” Molding
Compound (No Br, Sb) and Lead Free Finish/ RoHS
Compliant (Note 1)
