Product details

Adjustable shunt reference in SOT-23-3 — the BOM-fit decision

It delivers a user-programmable output from 1.233 V up to 10 V, set by two external resistors, with a ±1% initial tolerance and a 150 ppm/°C temperature coefficient.

Output range and bias current — what the ratings mean

The adjustable output spans from a minimum of 1.233 V to a maximum of 10 V, set by the resistor divider ratio. The 12 mA maximum output current defines the load-driving capability; the 73 µA cathode current is the minimum bias required to keep the shunt in regulation.

NRND status — design-in planning required

Buyers should evaluate a pin-compatible alternate for new BOMs.

Frequently asked questions

Is LM4041DEM3-ADJ obsolete or NRND?

It is not fully discontinued, but it is not recommended for new product designs. A pin-compatible alternative within the LM4041 family should be selected for new BOMs.

LM4041DEM3-ADJ vs LM4041AEM3-ADJ: what is the difference?

The primary difference is the initial tolerance grade. The LM4041DEM3-ADJ offers ±1% tolerance, while the LM4041AEM3-ADJ is a higher-grade variant with ±0.1% tolerance. Both are adjustable shunt references in the same SOT-23-3 package and share the same pinout.
