PROGRAMMABLE PRECISION SHUNT REGULATOR TL431Z/AZ /CZ
PROGRAMMABLE PRECISION REFERENCES
The TL431Z is three-terminal adjustable shunt regulator
with specified termal stability.
The output voltage may be set to any value between
V_REF(Approx. 2.5V) and 36V with two external resistors.
This device has a typical output inpedance of 0.2Ω.
Active output circuitry provides a very sharp turn-on
characteristic, making this device excellent
replacement for zener diodes in many application.
