Overview
The TLVH431NACDBZRR is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N family, housed in an SOT23 plastic surface-mounted package. It features A-Grade reference voltage tolerance of 1.0%, with a typical Vref of 1240 mV at 25 °C. The output voltage is programmable between approximately 1.24 V and 14 V using two external resistors. Operating conditions specify a cathode current range of 0.08 mA to 70 mA and a maximum cathode-anode voltage of 14 V. The device exhibits low output noise and a typical dynamic impedance of 0.1 Ω.
Feature Summary
- Programmable output voltage up to 14 V via external resistors
- A-Grade reference voltage tolerance of 1.0%
- Low output noise characteristics
- Typical dynamic output impedance of 0.1 Ω
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 that the specific ordering suffix matches the required pinning configuration and temperature grade. Confirm the component status aligns with project requirements, as this data sheet indicates non-automotive qualification. Ensure compatibility with standard SOT23 footprints during PCB layout planning.
Selection Notes
Select this variant when a 1.0% reference voltage tolerance is required for higher accuracy applications compared to the standard 1.5% grade. Consider the mirrored pinning option if the MQDBZR suffix is needed for board layout flexibility. Evaluate thermal resistance values based on the intended PCB copper area and mounting method.
Part Context
This component belongs to the TLVH431N family of low-voltage adjustable precision shunt regulators. The family includes variants with different temperature ranges and reference voltage tolerances. The 'NA' designation specifically denotes the A-Grade 1.0% tolerance version within the commercial and extended industrial temperature specifications provided by Nexperia.
Replacement Considerations
Direct substitutes include other TLVH431N family members such as TLVH431NCDBZR or TLVH431NACDBZR, depending on the required tolerance and pinning configuration. Verify pinout compatibility before swapping between normal and mirrored pinning versions.
