TLVH431AIL5T Working Principle

The TLVH431AIL5T operates on the principle of a bandgap reference. Bandgap references generate a voltage which is independent of temperature and current; these circuits use a bipolar junction that is transmuted into a diode connected pair which serves as a heat sink for transistors. The bandgap is built up by running the base current of the transistor in reverse bias mode, hence the reference voltage is built up by the difference between the forward voltage of the diode, which is independent to the temperature and environment. The reference voltage is used to regulate the current in the circuit and provide a stable output voltage.
