TLVH431BCDCKTG4

Overview

The TLVH431BCDCKTG4 is a low-voltage adjustable precision shunt regulator from Texas Instruments, housed in a SC-70-6 package. It features an output voltage range of 1.24 V to 18 V with an initial accuracy of ±0.5%. The device supports a maximum cathode current of 70 mA and operates within a temperature range of -40°C to +125°C. It utilizes a standard SOT-23-3 compatible pinout adapted for the smaller footprint.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to 18 V
• High precision reference with ±0.5% initial accuracy tolerance
• Wide operating current range supporting up to 70 mA cathode current
• Extended industrial temperature operation from -40°C to +125°C

Applications

• Battery-powered equipment requiring precise voltage monitoring
• Portable devices needing compact power management solutions
• Industrial control systems utilizing shunt regulation
• General-purpose voltage reference circuits in space-constrained designs

Procurement Notes

Verify the specific suffix 'TG4' confirms the tape-and-reel packaging format and lead-free composition as per Texas Instruments standards. Ensure the SC-70-6 footprint matches your PCB layout constraints. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement orders.

Selection Notes

Select this component when a small surface-mount footprint is required alongside high precision. The 70 mA current capacity suits applications demanding moderate load handling without external pass transistors. Compare against standard TLV431 variants if higher current or different package types are needed. Verify thermal performance requirements align with the SC-70-6 package capabilities.

Part Context

This part belongs to the TLVH431B family of low-voltage adjustable precision shunt regulators. It serves as a compact alternative to larger packages while maintaining high accuracy. The series is designed for modern electronics where board space is limited but regulatory precision remains critical for stable power supply operations.

Replacement Considerations

Direct substitutes include other TLVH431B variants in SC-70-6 such as TLVH431ACDCKRG4 or TLVH431BCDCKR. Verify that replacement parts maintain the same 70 mA current rating and ±0.5% accuracy specifications to ensure circuit compatibility.
