TFTL431
PROGRAMMABLE PRECISION REFERENCES
The TL431 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.
