Overview
The TLVH431NAQDBZR-QVL is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N-Q family. It operates within an output voltage range of 1.24 V to 14 V, set by two external resistors. This A-Grade device features a reference voltage tolerance of 1.0% and supports a cathode current range of 0.08 mA to 70 mA. Qualified according to AEC-Q100 Grade 1, it functions reliably across an ambient temperature range of -40 °C to +125 °C. The component utilizes a SOT23 (TO-236AB) surface-mounted package with normal pinning configuration.
Feature Summary
- A-Grade reference voltage tolerance of 1.0% for high precision applications
- Qualified according to AEC-Q100 Grade 1 for automotive reliability
- Low output noise and typical dynamic impedance of 0.1 Ω
- Active output circuitry provides sharp turn-on characteristics
Applications
- Shunt regulator circuits
- Precision constant current sink
- Isolated feedback loop for Switch Mode Power Supply (SMPS)
- Precision current limiter
Procurement Notes
Verify that the ordering suffix matches the specific pinning configuration required for the design. Confirm the A-Grade designation ensures the 1.0% reference voltage tolerance. Ensure the selected package variant aligns with the PCB footprint specifications provided in the datasheet. Check for any recent Product Change Notifications regarding manufacturing site codes or material updates before finalizing procurement.
Selection Notes
Select this component when automotive qualification and tight reference voltage accuracy are required. The A-Grade specification offers superior tolerance compared to standard grades. Verify that the operating temperature range meets the application's environmental demands. Consider the mirrored versus normal pinning options based on the existing board layout constraints.
Part Context
This part belongs to the TLVH431N-Q family of low-voltage adjustable precision shunt regulators manufactured by Nexperia. The family includes variants with different temperature ranges and reference voltage tolerances. The Q-suffix indicates automotive qualification under AEC-Q100 standards. The NA prefix specifically denotes the A-Grade performance level within this product line.
Replacement Considerations
Compatible substitutes within the same family include TLVH431NAIDBZR-Q and TLVH431NAMQDBZR-Q. Note that these alternatives may differ in temperature range or pinning configuration. Verify electrical parameters and package dimensions before substitution.
