TLV431ACDBVR

Overview

The TLV431ACDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 6 V and provides an adjustable output voltage from 1.24 V to 6 V. The device features an initial accuracy of ±1% and a maximum temperature coefficient of 138 ppm/°C. It supports a cathode current range from 80 µA to 15 mA and utilizes a 5-pin SOT-23 surface-mount package.

Feature Summary

• Provides adjustable reference voltage functionality with high precision for stable circuit operation
• Operates as a shunt regulator suitable for low-voltage power management applications
• Utilizes a compact surface-mount package design for efficient board space utilization

Applications

• Portable equipment requiring precise voltage references
• DC-to-DC converter feedback loops
• Post-regulators in power supply circuits

Procurement Notes

Verify the specific suffix DBVR indicates tape and reel packaging when sourcing. Confirm the component matches the 5-pin SOT-23 footprint required by the target PCB layout. Ensure the operating environment stays within the specified temperature range for optimal accuracy performance.

Selection Notes

Select this component when a low-voltage, high-precision adjustable reference is needed in a small form factor. It serves as a direct replacement for standard TL431 devices in low-voltage designs where the higher input voltage capability of the TL431 is unnecessary. Consider the 15 mA current limit for load requirements.

Part Context

This part belongs to the TLV431 family of low-voltage adjustable shunt regulators. It offers improved performance over traditional Zener diodes and standard TL431s in low-voltage scenarios. The device integrates a 1.24 V internal reference with an error amplifier to regulate the output voltage precisely across the specified operating conditions.

Replacement Considerations

TLV431ACDBZT is a compatible alternative in a 3-pin SOT-23 package.
