Product details

10V shunt reference in a SOT-23-3 footprint

The LM4040CIM3X-10 is a precision 10V shunt voltage reference from the LM4040 family, offered in a three-pin SOT-23-3 surface-mount package.

Sourcing is limited to independent distribution and surplus inventory channels.

Key parametric limits for the BOM review

As a shunt reference, the LM4040CIM3X-10 regulates by shunting current through the cathode to ground. Design the bias resistor to supply at least 100 µA through the reference under all load conditions, and ensure the total current through the device does not exceed 15 mA to stay within the power dissipation limits of the SOT-23-3 package. The ±0.5% tolerance bin (C grade) represents a middle accuracy tier in the LM4040 family, between the ±0.1% A grade and the ±1% D grade.

Frequently asked questions
