TLVH431BCLPE3 Adjustable Precision Shunt Regulator

The TLVH431BCLPE3 is a low-voltage three-terminal adjustable shunt regulator with a specified thermal stability over applicable automotive, commercial, and military temperature ranges. Manufactured by Texas Instruments, this device offers excellent performance in a small form factor, making it suitable for a wide range of applications.

This shunt regulator can be programmed from Vref (approximately 1.24 volts) up to 18 volts with two external resistors. These devices have a typical dynamic output impedance of 0.22 ohms. Active output circuitry provides a very sharp turn-on characteristic, making the TLVH431BCLPE3 excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.

The TLVH431BCLPE3 is offered in a TO-92 package, which is widely preferred for commercial and industrial applications due to its ease of handling and mounting. The small size of the TO-92 package allows for compact PCB design and is beneficial for applications where space is a premium. Furthermore, the device's low operational current contributes to energy efficiency in the end application.
