Overview
The TLVH431NMQDBZRVL 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 between 0.08 mA and 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 mirrored pinning in an SOT23 package, where Pin 1 is Cathode, Pin 2 is Reference, and Pin 3 is Anode. The unit is designed for commercial temperature ranges up to 125 °C.
Feature Summary
- Programmable output voltage adjustable via external resistors
- Mirrored pin configuration for flexible PCB layout
- Low dynamic output impedance for stable regulation
Applications
- Shunt regulator circuits
- Precision constant current sinks
- Isolated feedback loops for Switch Mode Power Supplies
Procurement Notes
Verify that the specific suffix matches the required pinning configuration, as this variant uses mirrored pinning distinct from standard versions. Confirm the component meets non-automotive qualification standards suitable for commercial applications. Ensure thermal management aligns with the specified junction-to-ambient resistance values for the target operating environment.
Selection Notes
Select this part when a low-cost, high-precision shunt regulator with mirrored pinout is required. The A-Grade tolerance ensures tighter reference voltage accuracy compared to standard grades. Verify that the application circuit remains stable across the full operating temperature range and load capacitance conditions defined in the datasheet.
Part Context
This component belongs to the TLVH431N family of adjustable precision shunt regulators manufactured by Nexperia. The family includes variants with different temperature ratings and reference voltage tolerances. This specific model represents the A-Grade version with extended temperature support and specialized pinning for design flexibility.
Replacement Considerations
Direct substitutes include other TLVH431N family members such as TLVH431NAIDBZR or TLVH431NAMQDBZR, provided the pinning configuration and tolerance requirements match the design specifications.
