Frequently Asked Questions
What is the adjustable output voltage range of the TLVH431QDCKT, and how is it set?
The TLVH431QDCKT output voltage is adjustable from 1.24 V to 18 V using an external resistor divider connected to the REF pin. This range covers most low-voltage automotive rail references and allows designers to tailor the regulation point precisely without additional components, supporting output currents up to 80 mA.
Which automotive control modules can the TLVH431QDCKT support given its AEC-Q100 qualification?
As an AEC-Q100-qualified device, the TLVH431QDCKT is suitable for body control modules, ADAS sensor power rails, instrument cluster references, and powertrain ECUs operating over a -40 °C to +125 °C junction temperature range. The 1.5% initial accuracy ensures stable feedback in safety-relevant circuits without requiring post-production trimming.
How does the SOT-23 6-pin package of the TLVH431QDCKT compare to larger shunt-regulator packages for PCB area?
The 6-pin SOT-23 package occupies roughly 8 mm² of PCB area, significantly less than the TO-92 or SOIC-8 alternatives. This compact footprint enables high-density placement in automotive modules where board space is constrained, while still providing full 80 mA sink capability and a stable 1.24 V reference voltage at the REF pin.
