Frequently Asked Questions
What output voltage range can the TLVH431AIDCKT regulate, and what sets that range?
The TLVH431AIDCKT regulates its output from 1.24 V up to 18 V. The lower bound is the internal band-gap reference voltage of approximately 1.24 V, and the upper limit of 18 V is set by the absolute maximum cathode voltage rating. A simple resistor divider on the REF pin programs any target voltage within this 1.24 V–18 V window.
How much current can the TLVH431AIDCKT sink, and how does that affect SMPS feedback design?
The device can sink up to 80 mA through its cathode, which is sufficient to drive an optocoupler LED directly in an isolated flyback converter feedback path. This eliminates the need for a dedicated driver transistor, reducing component count by at least 2 parts and saving board space in a standard flyback design operating at output voltages up to 18 V.
For a compact load-switch protection circuit, what board area does the TLVH431AIDCKT's SOT-23-6 package occupy?
The 6-pin SOT-23 (JESD-30 code R-PDSO-G6) body measures approximately 1.6 mm × 2.9 mm with a maximum height of 1.45 mm, occupying roughly 4.6 mm² of PCB area. This compact footprint allows the shunt reference to be placed close to the feedback pin of a switching controller, minimizing noise pickup on the voltage-sense node.
When should a designer choose the TLVH431AIDCKT over a fixed 2.5 V or 5 V shunt reference?
When the target regulation voltage is non-standard—for example, 3.6 V for a Li-ion cell protection circuit or 12.5 V for a rail monitor—the TLVH431AIDCKT's 1.24 V–18 V adjustable range avoids stocking multiple fixed-voltage parts. With a single part number covering the full range and a 80 mA sink capability, it reduces procurement SKUs and inventory cost compared to maintaining separate 2.5 V, 5 V, and 12 V fixed references.
