10V shunt reference in a small SOT-23-3 — what it delivers
Shunt topology — design implications
As a shunt reference, the TL4050C10IDBZR behaves like a Zener diode — it requires a series resistor from the supply to set the bias current. The cathode current range runs from 103 µA minimum up to 15 mA maximum. That 103 µA floor is the minimum current to maintain regulation; below it the output voltage drifts. Design the bias resistor so the current stays above 103 µA across the full supply and load range, and stays under 15 mA to avoid exceeding the package dissipation in SOT-23-3.
It is an in-production part, so new designs can commit it without LTB risk.
