The TLVH431QLP: ROHS3 compliant per the manufacturer listing, which simplifies the compliance check for EU and UKCA markets without requiring an exemption review.
Adjustable shunt reference — key parametric fit
This is a shunt-type adjustable voltage reference with a minimum output of 1.24 V and a maximum of 18 V — the feedback divider sets the regulation point anywhere in that band, so one part number covers multiple voltage rails on the same BOM. Rated for 70 mA continuous output current and a cathode current as low as 100 µA — the low minimum operating current means it can serve as a precision bias reference in battery-powered or low-quiescent designs without wasting headroom. The ±1.5% tolerance is tighter than the standard TLV431's 2% grade — for a 2.5 V rail, that is ±37.5 mV max error at 25 °C, which suits 8-bit ADC reference or comparator threshold applications where the extra margin matters.
Housed in a TO-92-3 (TO-226AA) through-hole package — the three-lead inline footprint is a standard 0.1-inch pitch layout that hand-solders easily and fits protoboard or production wave-solder runs without a reflow profile. Supplied in Bulk packaging — the loose-tube format is typical for through-hole parts; for high-volume pick-and-place, check whether the reel or ammo-pack variant of the same die is preferred.
