TLVH431AIDBZR,215

Overview

The TLVH431AIDBZR,215 is a low voltage three-terminal adjustable precision shunt regulator manufactured by NXP Semiconductors. It operates within a cathode-anode voltage range of 1 V to 18 V and supports a sink current capability from 0.08 mA to 70 mA. The device features an A-Grade reference voltage tolerance of 1%, with a typical reference voltage of 1.24 V at 25 °C. It is housed in a SOT23 (TO-236AB) surface-mount package and is qualified to the AEC-Q100 Grade 1 standard for operation across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Programmable output voltage set between Vref and 18 V using two external resistors
• AEC-Q100 qualified for automotive applications with specified thermal stability
• Low output noise and high dynamic impedance characteristics
• Active output circuitry provides sharp turn-on performance

Applications

• Shunt regulator circuits
• Precision current limiter designs
• Precision constant current sinks
• Isolated feedback loops for Switch Mode Power Supplies

Procurement Notes

Verify the specific suffix '215' against official NXP documentation to confirm packing method details, as datasheet tables list generic tape and reel options without explicit suffix mapping. Ensure the component matches the SOT23 package outline and normal pinning configuration defined for the TLVH431AIDBZR type number. Confirm compliance with RoHS directives and lead finish specifications prior to integration.

Selection Notes

Select this component when an adjustable precision reference with automotive qualification is required. The A-Grade 1% tolerance offers tighter accuracy than the standard grade while maintaining cost efficiency compared to D-Grade options. Verify that the application load capacitance remains within the stability boundaries shown in the datasheet graphs to prevent oscillation during operation.

Part Context

This part belongs to the TLVH431 family of low voltage adjustable precision shunt regulators. The family includes Standard (1.5%), A-Grade (1%), and D-Grade (0.75%) variants. The TLVH431AIDBZR specifically denotes the A-Grade version in the SOT23 package with extended temperature coverage. Other family members include mirrored pinning versions and SOT753 packages.

Replacement Considerations

Direct substitutes within the same family include TLVH431AQDBZR (mirrored pinning) or TLVH431DQDBZR (higher precision). Cross-family replacements like the TL431 require verification of voltage ranges and pin compatibility.
