TLVH431NCDBZR-QVL

Overview

The TLVH431NCDBZR-Q is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N-Q family. It features a programmable output voltage range between Vref = 1.24 V and 14 V, set by two external resistors. This component belongs to the Standard grade with a reference voltage tolerance of 1.5%. It operates within an ambient temperature range of 0 °C to 70 °C and is housed in a SOT23 (TO-236AB) package with normal pinning configuration.

Feature Summary

Programmable output voltage up to 14 V
Qualified according to AEC-Q100 (grade 1)
Low output noise
Typical output impedance of 0.1 Ω

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 part number matches the required temperature range and tolerance grade. Confirm the pinning configuration aligns with the PCB footprint design, as mirrored pinning variants exist within the same family. Ensure compliance with automotive qualification standards if intended for vehicle electronics.

Selection Notes

Select this component when a low-cost, automotive-grade shunt regulator is needed for standard commercial temperature ranges. The 1.5% tolerance suits general regulation tasks where tighter precision is unnecessary. Consider alternative grades or wider temperature variants if operating conditions exceed 70 °C or require higher accuracy.

Part Context

This device is part of the TLVH431N-Q family of adjustable precision shunt regulators designed for automotive applications. The family includes variants with different reference voltage tolerances and extended temperature ranges, all sharing similar functional characteristics and packaging options to support diverse design requirements.

Replacement Considerations

Compatible substitutes include other parts from the TLVH431N-Q family such as TLVH431NAQDBZR-Q for improved tolerance or TLVH431NQDBZR-Q for extended temperature operation. Verify pin compatibility and thermal performance before substitution.
