TL431 is a three-terminal adjustable precision shunt voltage regulator integrated circuit. With the use of an external voltage divider, a TL431 can regulate voltages ranging from 2.5 to 36 V, at currents up 100 mA. The typical initial deviation of reference voltage from the nominal 2.495 V level is measured in millivolts, the maximum worst-case deviation is measured in tens of millivolts. The circuit can control power transistors directly; combinations of the TL431 with power MOS transistors are used in high efficiency, very low dropout linear regulator
Components:-
1. TL431 voltage regulator
2. 1N4007 Diode
3. 100uf Capacitor
4. 3.3K Resistor
5. 4.7K Resistor
6. 2A Diode
7. 3.9V Zener Diode
8. 10K Preset
