Technical details

10 V fixed shunt reference, ±0.2 % initial accuracy

It operates as a two-terminal shunt regulator, so no external series resistor is needed for the reference itself — just a single resistor from the supply to the cathode to set the bias current.

SOT-23-3 footprint and bias current budget

Housed in a three-pin SOT-23-3 package (also listed as TO-236-3 / SC-59), this reference takes up minimal board area — about 2.9 mm × 1.3 mm — so it fits into tight analog front-end sections alongside op-amps or ADCs. The cathode current can be as low as 103 µA, which keeps the quiescent power draw small in battery-powered gear. Maximum output current is 15 mA, so the reference can source a modest load or bias a downstream divider without an external buffer.
