Product details

Adjustable shunt reference in a SOT-23-3 footprint

The LM4041CIM3X-ADJ is an adjustable shunt voltage reference from Texas Instruments, delivering a ±0.5% initial tolerance across an output range from 1.233 V up to 10 V. It operates as a two-terminal shunt regulator — no external series pass element — and sinks a cathode current of 65 µA typical, with a maximum output current of 12 mA. The SOT-23-3 package (TO-236-3 / SC-59 compatible) keeps the board footprint small, making it a common choice for precision bias supplies, ADC references, and comparator thresholds in portable or space-constrained designs.

Temperature coefficient and noise floor

Wideband noise is specified at 20 µVrms over a 10 Hz to 10 kHz bandwidth — low enough for 10- to 12-bit ADC reference applications without additional filtering in most cases.

Frequently asked questions

What is the replacement for LM4041CIM3X-ADJ?

A functional replacement should be a ±0.5% adjustable shunt reference in a SOT-23-3 package with a 1.233 V minimum output and 100 ppm/°C temperature coefficient. The LM4041 family includes other adjustable and fixed-output variants — confirm the exact output range and tolerance grade for your BOM.

What is the tolerance and output range of LM4041CIM3X-ADJ?

Initial tolerance is ±0.5%. The output is adjustable from a minimum of 1.233 V up to a maximum of 10 V.

Is LM4041CIM3X-ADJ RoHS compliant?

The evidence does not explicitly state RoHS compliance status. Verify with the datasheet or a supplier quote for the specific date code lot.
