TLV431AIDBVTG4

Overview

The TLV431AIDBVTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It features an initial accuracy of 1% and operates within a temperature range of -40°C to +125°C. The device provides an adjustable output voltage ranging from 1.24V to 6V, with a maximum series VREF input voltage of 7V. It supports a maximum shunt current of 15mA and has a typical temperature coefficient of 138 ppm/°C. The component is housed in a SOT-23-5 surface-mount package.

Feature Summary

• Provides precise voltage regulation with 1% initial accuracy for stable reference applications
• Operates at low voltages with an adjustable output range starting from 1.24V
• Designed for extended industrial temperature environments up to 125°C

Applications

• Low-voltage power supply feedback loops
• Portable equipment voltage references
• Battery-powered system monitoring circuits

Procurement Notes

Verify the complete part number including the TG4 suffix to ensure compliance with specific environmental standards. Confirm the SOT-23-5 package variant matches the design footprint requirements. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments documentation before finalizing procurement plans.

Selection Notes

Select this component when a low-voltage precision reference is required with high thermal stability. The 1% accuracy suits applications demanding tighter tolerance than standard regulators. Ensure the operating voltage does not exceed the 7V maximum input limit. Consider the 15mA current capability against load requirements.

Part Context

This device belongs to the TLV431 family of adjustable precision shunt regulators. It serves as a low-voltage alternative to traditional bandgap references, offering comparable performance in a compact surface-mount package. The family is widely used in power management circuits requiring accurate voltage sensing and regulation.

Replacement Considerations

The TLV431AIDBVT is a compatible variant without the environmental suffix. Verify pinout compatibility when substituting with other shunt regulators.
