TLVH431NAIDBZRVL

Overview

The TLVH431NAIDBZRVL is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N family. It operates within a cathode-anode voltage range of Vref to 14 V and supports a sink current capability from 0.08 mA to 70 mA. The device features an A-Grade reference voltage tolerance of 1.0%, with a typical reference voltage of 1240 mV at 25 °C. It utilizes a SOT23 surface-mounted package with normal pinning configuration.

Feature Summary

• Programmable output voltage adjustable between approximately 1.24 V and 14 V using two external resistors.
• A-Grade reference voltage tolerance of 1.0% ensures high precision across operating conditions.
• Low output noise characteristics with a typical dynamic impedance of 0.1 Ω for stable regulation.
• Active output circuitry provides sharp turn-on characteristics suitable for replacing Zener diodes.

Applications

• Shunt regulator
• Precision current limiter
• Precision constant current sink
• Isolated feedback loop for Switch Mode Power Supply (SMPS)

Procurement Notes

Verify that the specific suffix 'VL' corresponds to the standard DBZR reel packaging or specific tape-and-reel variant defined in the official ordering information. Confirm the component meets the non-automotive qualification status as indicated by the TLVH431N family datasheet revision, ensuring it aligns with commercial application requirements rather than automotive standards.

Selection Notes

Select this component when a precise, low-noise shunt reference is required for commercial temperature ranges (-40 °C to +85 °C). The 1.0% tolerance makes it suitable for applications demanding tighter accuracy than standard grades. Ensure the design accommodates the minimum cathode current requirement of 55 μA for proper regulation and verify stability with load capacitance per the application guidelines.

Part Context

This part belongs to the TLVH431N family of adjustable precision shunt regulators manufactured by Nexperia. Unlike the automotive-qualified TLVH431N-Q variants, this family is designated for non-automotive use. The device serves as a compact, cost-effective alternative to discrete Zener diodes in power supply regulation and current limiting circuits.

Replacement Considerations

Direct replacements include other parts within the TLVH431N family such as TLVH431NAIDBZR. Verify pin compatibility, as mirrored pinning options exist within the family. Ensure the substitute maintains the required 1.0% A-Grade tolerance and SOT23 package dimensions for board-level interchangeability.
