TLVH431IDBZRG4

Overview

The TLVH431IDBZRG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a reference voltage range of 1.24 V to 18 V and features an initial accuracy of ±1.5%. The device supports a maximum cathode current of 70 mA and withstands a maximum series input voltage of 20 V. It utilizes an SOT-23-3 surface-mount package and functions across a temperature range of -40°C to +85°C.

Feature Summary

Provides adjustable precision voltage reference functionality in a compact surface-mount form factor
Designed for low-voltage applications with high accuracy specifications
Operates as a three-terminal shunt regulator without requiring shutdown control

Applications

Battery-powered equipment requiring precise voltage monitoring
Portable consumer electronics utilizing low-voltage power supplies
Industrial control systems needing stable reference voltages
Power management circuits in mobile devices

Procurement Notes

Verify the specific suffix RG4 indicates reel packaging when sourcing. Confirm the 1.5% accuracy grade matches design requirements. Ensure the SOT-23-3 footprint aligns with PCB layout constraints. Check RoHS compliance status for environmental regulations. Validate operating temperature range suitability for the intended application environment.

Selection Notes

Select this component when a low-voltage adjustable reference is required with moderate accuracy. Compare against TLV431 series if higher current or different voltage ranges are needed. Consider thermal performance within the specified -40°C to +85°C range. Evaluate pin compatibility with existing SOT-23-3 designs. Assess cost-effectiveness relative to higher precision alternatives.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators from Texas Instruments. It shares architectural similarities with the TLV431 but offers extended voltage capabilities up to 18 V. The IDBZR designation specifies the accuracy grade, package type, and tape-and-reel packaging configuration for automated assembly processes.
