Overview
The TLVH431NIDBZR is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N family, housed in an SOT23 plastic surface-mounted package. It operates within a temperature range of -40 °C to +85 °C and features an A-Grade reference voltage tolerance of 1.0%. The cathode-anode voltage (VKA) ranges up to 14 V, with a sink current capability between 0.08 mA and 70 mA. The typical output impedance is 0.1 Ω, and the internal reference voltage is approximately 1.24 V.
Feature Summary
- Programmable output voltage set by two external resistors
- Low output noise characteristics
- Sharp turn-on active output circuitry
Applications
- Shunt regulator
- Precision current limiter
- Isolated feedback loop for Switch Mode Power Supply (SMPS)
Procurement Notes
Verify that the specific part number matches the required pinning configuration, as mirrored pinning variants exist within the same family. Confirm the component meets non-automotive qualification standards, as indicated by the datasheet revision history. Ensure design compliance with absolute maximum ratings to prevent permanent device damage during operation.
Selection Notes
Select this variant for applications requiring an extended industrial temperature range of -40 °C to +85 °C. The A-Grade specification provides tighter reference voltage tolerance compared to standard grades. Verify compatibility with the target PCB footprint, noting the SOT23 package outline dimensions and soldering requirements for reliable surface-mount assembly.
Part Context
This component belongs to the TLVH431N family of adjustable precision shunt regulators. Unlike automotive-qualified counterparts, this specific series is designated for commercial use. The family shares common functional diagrams and thermal characteristics but varies in temperature ratings and reference voltage tolerances across different suffixes.
Replacement Considerations
Direct replacements include other TLVH431N family members such as TLVH431NAIDBZR or TLVH431NCDBZR, provided the temperature grade and pinning configuration align with the existing design constraints.
