ZTL431/ZTL432
COST EFFECTIVE ADJUSTABLE PRECISION SHUNT REGULATOR
Description
The ZTL431 and ZTL432 are three terminal adjustable
shunt regulators 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.
The ZTL432 has the same electrical specifications as the
ZTL431 but has a different pin out in SOT23 (F-suffix) and
SOT23F (FF-suffix).
Both variants are available in 2 grades with initial
tolerances of 1% and 0.5% for the A and B grades
respectively.
These are functionally equivalent to the TL431/ TL432
except for maximum operation voltage, and have an
ambient temperature range of -40 to 125°C as standard.
Features
• Temperature range ................ -40 to 125°C
• Reference voltage tolerance at 25°C
o 0.5%.......................................B grade
o 1% .........................................A grade
• 0.2Ω typical output impedance
• Sink current capability…….. 1mA to 100mA
• Adjustable output voltage……VREF to 20V
Applications
• Opto-coupler linearization
• Linear regulators
• Improved zener
• Variable reference
