Tl431 Schaltung. Tl431 d tl431a b series ncv431a b series scv431a programmable precision references the tl431a b integrated circuits are three terminal programmable shunt regulator diodes. The tl431 is a full fledged ic with a precision voltage level reference a comparator and the active transistor all bundled up inside.
It is a zener diode whose voltage rating can be adjusted based on the value of resistors connected to the reference pin. Electrical specifications as the tl431 device but has different pinouts for the dbv dbz and pk packages. The output voltage can be dimensioned using just two resistors across the specified pin outs of the device.
The tl431 a b integrated circuits are three terminal programmable shunt regulator diodes.
