TLVH431AIDCKR

Overview

The TLVH431AIDCKR is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 1.24 V to 18 V and features an initial accuracy tolerance of ±1%. The device supports a maximum cathode current of 70 mA and maintains a minimum cathode current of 100 µA for regulation. It is housed in a SC-70-6 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides adjustable reference voltage output from 1.24 V to 18 V with high initial accuracy.
• Supports wide operating current range up to 70 mA for flexible circuit design.
• Designed for compact applications using the small SC-70-6 surface-mount package.

Applications

• Portable battery-powered equipment requiring precise voltage references
• Microcontroller power supply monitoring circuits
• Linear regulator feedback networks

Procurement Notes

Verify the specific suffix 'A' indicates the ±1% accuracy grade and 'I' denotes the industrial temperature range (-40°C to +85°C). Confirm the 'DCKR' suffix corresponds to the SC-70-6 package and tape-and-reel quantity. Ensure compatibility with RoHS3 standards as documented in official specifications.

Selection Notes

Select this component when a low-voltage, high-accuracy reference is required in a minimal footprint. The ±1% tolerance offers better precision than standard 1.5% variants. Consider the 70 mA current capability for driving load requirements without external amplification.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering superior stability and lower dynamic impedance. The family includes various packages and accuracy grades to suit different space and performance constraints.
