TLVH431BCDBZRG4

Overview

The TLVH431BCDBZRG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a low-voltage range, providing an output voltage adjustable from 1.24 V to 18 V. The device features an initial accuracy of 0.5% and a maximum temperature coefficient of 92 ppm/°C. It supports a maximum cathode current of 70 mA and a minimum operating current of 100 µA. The component is housed in a SOT-23-3 surface-mount package and functions with a maximum input voltage of 20 V. It is rated for operation between -40°C and +125°C.

Feature Summary

Provides precise adjustable voltage reference functionality with high initial accuracy.
Supports wide operating current range suitable for various load conditions.
Designed for low-voltage applications with extended industrial temperature coverage.

Applications

Battery-powered equipment requiring stable voltage references
Portable devices utilizing low-voltage power supplies
Industrial control systems needing precision regulation

Procurement Notes

Verify the specific suffix RG4 indicates reel packaging when ordering. Confirm that the AEC-Q100 qualification aligns with automotive requirements if applicable. Ensure the SOT-23-3 footprint matches the target PCB design. Check RoHS compliance status for environmental regulations. Validate the 100 µA minimum current requirement against the circuit's standby load.

Selection Notes

Select this component when a low-voltage adjustable reference is required with 0.5% accuracy. Consider the 70 mA cathode current limit for load driving capabilities. Evaluate the -40°C to +125°C temperature range against environmental constraints. Compare the 92 ppm/°C temperature coefficient against stability needs. Ensure the SOT-23-3 package fits the available board space.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a compact alternative to standard TL431 devices for applications where supply voltage is limited. The family offers various accuracy grades and package options to suit different design constraints.
