TLVH431NQDBZR-QVL

Overview

The TLVH431NQDBZR-QVL is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N-Q family. It features an output voltage range between Vref (1.24 V) and 14 V, set by two external resistors. The device has a standard reference voltage tolerance of 1.5%, with a typical value of 1240 mV at 25 °C. It operates within a temperature range of -40 °C to +125 °C and is qualified according to AEC-Q100 Grade 1. The cathode current ranges from 0.08 mA to 70 mA, and it offers a typical dynamic impedance of 0.1 Ω in an SOT23 package.

Feature Summary

AEC-Q100 Grade 1 qualification for automotive applications
Adjustable output voltage up to 14 V via external resistors
Low output noise and high stability characteristics
Standard grade reference voltage tolerance of 1.5%

Applications

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

Procurement Notes

Verify that the specific suffix QVL corresponds to the standard pinning configuration defined for the TLVH431NQDBZR-Q type number in the official datasheet. Confirm the component meets the required AEC-Q100 Grade 1 automotive standards and matches the specified -40 °C to +125 °C operating temperature range before finalizing procurement specifications.

Selection Notes

Select this component when an adjustable shunt regulator with automotive reliability is required. Ensure the application voltage does not exceed the 14 V maximum limit. Verify that the external resistor network can provide the necessary bias current within the 0.08 mA to 70 mA operational window. Consider the mirrored pinning option if layout constraints require alternative terminal arrangements.

Part Context

This part belongs to the TLVH431N-Q family of low-voltage adjustable precision shunt regulators designed for robust performance in demanding environments. The family includes variants with different tolerances and temperature ranges, all sharing the same core functionality and SOT23 packaging to facilitate easy integration into various power management and signal conditioning circuits.

Replacement Considerations

Compatible substitutes within the same family include TLVH431NCDBZR-Q, TLVH431NIDBZR-Q, and TLVH431NMQDBZR-Q. These alternatives share identical electrical characteristics but differ in reference voltage tolerance or pinning configuration. Ensure the replacement matches the specific tolerance and thermal requirements of the original design.
