TL431
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.
FEATURES
● Equivalent Full Range Temperature Coefficient 50PPM/℃
● Temperature Compensated For Operation Over
Full Rate Operating Temperature Range
● Adjustable Output Voltage
● Fast Turn-on Response
● Sink Current Capability 1㎃ to 100㎃
● Low (0.2Ω Typ.) Dynamic Output Impedance
● Low Output Noise
