TLV431BCDBVR

Overview

The TLV431BCDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It provides an initial accuracy of ±0.5% and operates with a reference voltage range from 1.24V to 6V. The device supports a maximum cathode current of 15 mA and functions within a supply voltage range of 2.5V to 36V. It features a temperature coefficient of 138 ppm/°C and operates across an extended temperature range from -40°C to +125°C. The component is housed in a compact SOT-23-5 surface-mount package, designed for space-constrained applications requiring stable voltage referencing.

Feature Summary

• Provides high-precision voltage regulation with ±0.5% initial accuracy
• Operates effectively at low voltages starting from 2.5V
• Supports wide operating current ranges up to 15 mA
• Ensures thermal stability with a low temperature coefficient

Applications

• Precision voltage regulation in industrial control systems
• Medical devices and equipment
• Aerospace and defense electronics

Procurement Notes

Verify the specific suffix DBVR confirms the SOT-23-5 tape and reel packaging configuration. Ensure the BC sub-code aligns with the required ±0.5% accuracy specification for your design. Confirm RoHS compliance status matches project requirements. Validate that the 15 mA current limit meets the load demands. Check for any recent lifecycle notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when precise voltage referencing is needed in low-voltage environments. The ±0.5% accuracy suits applications demanding tight tolerance. The SOT-23-5 package offers a small footprint for dense PCB layouts. Consider the 15 mA current capability against load requirements. The wide temperature range ensures reliability in harsh operational conditions compared to standard commercial grade parts.

Part Context

This part belongs to the TLV431 family of adjustable shunt regulators. It serves as a drop-in replacement for standard TL431 devices in many designs but offers improved performance at lower supply voltages. The family is widely used in power supplies and battery-operated devices. The BC variant specifically denotes the tighter accuracy bin within the product line.

Replacement Considerations

The TLV431BQDBVR is a qualified alternative offering similar functionality with potentially different manufacturing lot characteristics. Verify pin compatibility and electrical specifications match before substitution.
