Overview
The TLVH431NQDBZR is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N family, housed in an SOT23 plastic surface-mounted package. It features normal pinning configuration with cathode-anode voltage up to 14 V and sink current capability ranging from 0.08 mA to 70 mA. The device offers A-Grade reference voltage tolerance of 1.0%, with a typical reference voltage of 1240 mV at 25 °C. Operating temperature range extends from -40 °C to +125 °C, supporting applications requiring thermal stability.
Feature Summary
- Programmable output voltage adjustable between approximately 1.24 V and 14 V using two external resistors
- Low output noise with typical dynamic cathode-anode impedance of 0.1 Ω
- Active output circuitry provides sharp turn-on characteristic for effective regulation
Applications
- Shunt regulator circuits
- Precision current limiter designs
- Isolated feedback loops for Switch Mode Power Supplies (SMPS)
Procurement Notes
Verify the specific suffix 'Q' indicates the extended temperature range (-40 °C to +125 °C) and 1.0% tolerance grade. Confirm the 'BZRR' suffix corresponds to the SOT23 package and reel packaging format as specified in the ordering information table. Ensure compatibility with standard SOT23 footprints during PCB layout.
Selection Notes
Select this component when precise voltage referencing is required across wide temperature variations. The A-Grade tolerance ensures tighter accuracy compared to standard grades. Verify that the application load capacitance remains within stable operating boundaries defined in the datasheet characteristics to prevent oscillation.
Part Context
This part belongs to the TLVH431N family of adjustable precision shunt regulators manufactured by Nexperia. The family includes variants with different tolerances and temperature ranges, all utilizing the same SOT23 package footprint. The non-automotive qualified version distinguishes itself from the automotive-grade -Q series products available in the same lineup.
