TLVH431NACDBZR-QR

Overview

The TLVH431NACDBZR-QR is an adjustable precision shunt regulator from the Nexperia TLVH431N-Q family, housed in a SOT23 (TO-236AB) package with normal pinning. It features A-Grade reference voltage tolerance of 1.0%, with a typical Vref of 1240 mV at 25 °C and IK = 10 mA. The device supports programmable output voltages up to 14 V set by external resistors, operates within a cathode current range of 0.08 mA to 70 mA, and maintains a typical dynamic impedance of 0.1 Ω. Qualified under AEC-Q100 Grade 1 for automotive use.

Feature Summary

A-Grade reference voltage tolerance of 1.0% ensures high precision regulation.
Low output noise and typical dynamic impedance of 0.1 Ω enhance signal integrity.
Active output circuitry provides sharp turn-on characteristics suitable for switching applications.

Applications

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

Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's latest documentation to confirm the reel packaging configuration and manufacturing site code. Ensure the design accounts for the standard pinning configuration defined for non-MQ variants. Confirm that the application environment falls within the specified operating temperature ranges for the selected grade.

Selection Notes

Select this component when a 1.0% reference voltage tolerance is required for precision applications. The SOT23 package offers a compact footprint for surface-mount designs. Verify that the load capacitance requirements are met to ensure stability across the full operating temperature range, as performance depends on capacitor ESR.

Part Context

This part belongs to the TLVH431N-Q family of three-terminal adjustable shunt regulators designed for automotive and commercial environments. The family includes variants with different temperature grades and tolerances, utilizing either normal or mirrored pinning configurations depending on the ordering suffix.
