Overview
The Nexperia TL431ACDBZRVL is a programmable shunt voltage reference housed in an SOT-23-3 surface-mount package. It provides a stable reference voltage with an initial accuracy of ±1%. The device operates within a temperature range of 0°C to +70°C and supports an output voltage range from 2.4 V to 36 V, set by two external resistors. It features a typical output impedance of 0.2 Ω and a sink current capability between 1 mA and 100 mA. The component is RoHS compliant and designed for precision applications requiring low noise and high stability.
Feature Summary
- Programmable output voltage adjustable via external resistors
- High initial accuracy with ±1% tolerance
- Low output impedance for stable regulation
- Compact SOT-23-3 surface-mount packaging
Applications
- Shunt regulators
- Precision current limiters
- Isolated feedback loops for Switch Mode Power Supplies (SMPS)
Procurement Notes
Verify the specific suffix 'VL' against official Nexperia documentation to confirm reel specifications and tape-and-reel dimensions. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Confirm that the standard commercial temperature range meets the operational requirements of the target application environment before finalizing procurement.
Selection Notes
Select this component when a precise, adjustable voltage reference is required in space-constrained designs. The ±1% accuracy makes it suitable for applications demanding tighter tolerances than standard grades. Consider the 0°C to +70°C operating range to ensure suitability for the intended environmental conditions. Verify that the 100 mA sink current capability aligns with the circuit's load requirements.
Part Context
This part belongs to the TL431 family of three-terminal shunt regulators manufactured by Nexperia. The family offers various accuracy grades and temperature ranges. The 'A' designation indicates the 1% accuracy grade, while 'C' specifies the commercial temperature range. The 'DBZR' suffix denotes the SOT-23-3 package and reel packaging format.
Replacement Considerations
Compatible alternatives include TL431ACDBZR and TL431ACDBZRVL. Verify pinout compatibility and electrical parameters such as reference voltage tolerance and operating temperature range when substituting.
