Product details

Adjustable shunt reference — 1.212 V to 10 V output

It delivers an output voltage adjustable from a minimum of 1.212 V up to a maximum of 10 V, set by two external resistors.

NRND — plan last-time-buy or alternate

For existing BOMs, procurement should evaluate last-time-buy quantities or qualify an alternate shunt reference with the same SOT-23-3 footprint and ±0.1% tolerance grade.

12 mA output, 65 µA cathode current

The shunt reference can sink up to 12 mA of output current and requires a minimum cathode current of 65 µA for regulation. The 20 µVrms noise (10 Hz to 10 kHz) is low enough for 12-bit ADC reference applications without additional filtering.

Frequently asked questions

What is the output voltage range of LM4051AIM3-ADJ?

Buyers need to confirm the adjustable range matches their design requirement before selecting this reference.

Is LM4051AIM3-ADJ obsolete or recommended for new designs?

As a Not For New Designs part, engineers must decide quickly if they can still use it or need an alternative.

Where can I buy LM4051AIM3-ADJ in stock?

Sourcing buyers need immediate distributor availability to fill BOM lines without delay.

What is the equivalent or replacement for LM4051AIM3-ADJ?

Designers or brokers need a drop-in alternative due to NRND status or supply constraints.

What is the pinout and package of LM4051AIM3-ADJ?

Design engineers validate PCB footprint compatibility; maintenance techs need pin mapping for replacement.

How much does LM4051AIM3-ADJ cost in volume?

Pricing drives commercial decisions for both prototype and production runs.
