Product details

It delivers a stable output with a ±0.5% initial tolerance and a temperature coefficient of 100ppm/°C, making it suitable for ADC/DAC references, comparator thresholds, and power-supply monitoring in industrial control and instrumentation.

Package and mounting — through-hole TO-92

Housed in a TO-226-3 / TO-92-3 (TO-226AA) through-hole package, the LM4040C20ILP mounts directly into a PCB or socket without reflow. The through-hole form factor is common in breadboard prototyping, MRO repair, and low-volume builds where hand-soldering is preferred over SMD rework.

Frequently asked questions

What is LM4040C20ILP's listed tolerance?

The initial tolerance is ±0.5%. This is a precision-grade specification — the output voltage stays within 2.048V ±10.24 mV at 25°C, which sets the accuracy floor for the reference in the application.
