Product details

Adjustable shunt reference in a TO-92 — what it fits

It delivers a programmable output from a minimum of 1.233 V up to 10 V, set by two external resistors.

Output range and bias current — the design decisions

The adjustable output from 1.233 V to 10 V covers common reference voltages. Setting the output requires a resistor divider from the output to the ADJ pin; the reference's internal bandgap drives the ADJ pin to 1.233 V.

The TO-92 package is not hermetic; conformal coating is advisable in humid or condensing conditions.

No last-time-buy notice is in effect. For a production BOM, this part carries no imminent obsolescence risk. The through-hole TO-92 package means it is a candidate for legacy board repairs or new designs where surface-mount assembly is not available.

Frequently asked questions

What is the typical cathode current for LM4041DIZ-ADJ/LFT1?

The minimum cathode current is 70 µA. The device can sink up to 12 mA maximum. The bias circuit must ensure at least 70 µA flows through the shunt for proper regulation.

Can I use LM4041DIZ-ADJ/LFT1 as a 2.5V reference?

Yes. Set the output to 2.5 V by choosing the appropriate resistor divider between the output and the ADJ pin. The adjustable range from 1.233 V to 10 V covers 2.5 V.

How does LM4041DIZ-ADJ/LFT1 compare to the LM4132AMF-4.1/NOPB?

The LM4132AMF-4.1/NOPB is a fixed 4.096 V series reference with ±0.05% tolerance and 20 ppm/°C drift, surface-mount in SOT-23. The LM4041DIZ-ADJ/LFT1 is a through-hole adjustable shunt reference with ±1% tolerance and 150 ppm/°C drift. The LM4132 offers higher accuracy and lower drift for precision 4.096 V rails, but is fixed-output and surface-mount only. The LM4041 is the choice when you need an adjustable output or a through-hole package.
