Product details

The 15 mA output current capability lets it bias multiple loads or an external buffer, while the 103 µA cathode current keeps quiescent draw low in battery-powered designs.

NRND and RoHS non-compliant — plan the last-time-buy

SOT-23-3 footprint — compact but no second source on record

Housed in a SOT-23-3 (TO-236-3, SC-59) surface-mount package, this reference takes minimal board area and suits dense layouts. The three-pin shunt configuration — cathode, anode, and no-connect — is standard for this reference type.

Frequently asked questions

What is the output voltage and tolerance of LM4040AIM3X-10?

Buyers need to confirm if this part meets their voltage reference requirements.

Is LM4040AIM3X-10 still in production or is it obsolete?

The NRND status means it's not for new designs; buyers need to know if they can still source it or if they need a replacement.

Where can I buy LM4040AIM3X-10 in stock?

Inventory availability directly affects purchasing decisions and project timelines.

What is a replacement or equivalent for LM4040AIM3X-10?

With NRND status, buyers need alternative parts for new designs or if supply runs out.

What is the package and pinout of LM4040AIM3X-10?

Design engineers need to validate footprint compatibility and PCB layout.

What is the pinout of LM4040AIM3X-10?

Essential for design-in and validation of the circuit connection.
