Product details

Its shunt architecture means it operates like a two-terminal Zener — it sinks current from the supply through a series resistor, regulating the output to 1.225 V without needing a separate load capacitor for stability. The ±0.1% initial tolerance eliminates the need for external trimming in most 12-bit ADC reference applications, saving board space and calibration time during production.

No stock-holding claim — each order is quoted to the BOM quantity.

Package and footprint — SC-70-5 for dense boards

Housed in a 5-pin SC-70-5 (also SOT-353) surface-mount package, the LM4041A12IDCKR occupies minimal board area. The shunt reference is a two-terminal device.
