The TLVH431AQLP from Texas Instruments is a high-performance, low-voltage adjustable precision shunt regulator that offers excellent accuracy and stability. This device is a three-terminal adjustable shunt regulator with a specified thermal stability over applicable industrial and commercial temperature ranges. The output voltage can be set to any value between Vref (approximately 1.24 volts) and 18 volts with two external resistors.
This regulator features a typical dynamic output impedance of 0.2 ohms. Active output circuitry provides a very sharp turn-on characteristic, making this device excellent for use as a low-voltage reference in digital systems, where the desired output voltage is a direct function of the input voltage. The TLVH431AQLP is also ideal for use in portable electronics due to its low operational current characteristics.
