Overview
The TLVH431NCDBZRVL 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 a standard reference voltage tolerance of 1.5%, with a typical reference voltage of 1240 mV at 25 °C. It utilizes an SOT23 surface-mounted package with normal pinning configuration.
Feature Summary
- Programmable output voltage up to 14 V using two external resistors
- Low output noise characteristics for stable regulation
- Typical dynamic output impedance of 0.1 Ω
- Wide sink current capability ranging from 0.08 mA to 70 mA
Applications
- Shunt regulator circuits
- Precision current limiter designs
- Precision constant current sink implementations
- Isolated feedback loops for Switch Mode Power Supplies (SMPS)
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm package type, temperature grade, and marking codes. Confirm that the component meets required automotive or commercial qualification standards as specified in the latest product data sheet revision before finalizing procurement specifications.
Selection Notes
Select this component when a low-voltage adjustable shunt regulator with standard 1.5% reference voltage tolerance is required. Ensure the application circuit maintains the cathode current within the 0.08 mA to 70 mA operating range. Verify thermal dissipation requirements based on the specific PCB mounting conditions and ambient temperature limits defined in the datasheet.
Part Context
This part belongs to the TLVH431N family of non-automotive qualified adjustable precision shunt regulators. The 'N' designation indicates it is not automotive qualified. The 'C' suffix denotes the standard 1.5% reference voltage tolerance grade. The 'DBZR' indicates the SOT23 package with tape and reel packaging.
Replacement Considerations
Compatible substitutes include other parts within the TLVH431N family such as TLVH431ACDBZR for tighter tolerance or TLVH431IDBZR for extended temperature ranges. Verify pinning configuration compatibility, as mirrored pinning variants exist within the same family.
