Description

Key Features of the LM4041 Series:

Automotive and Industrial Temperature Ranges:

The LM4041 is AEC-Q100 qualified, with versions for both automotive (-40°C to +125°C) and industrial (-40°C to +85°C) environments.

Compact Packages:

Available in small packages like SOT-23, SC70, and TO-92, it is perfect for space-constrained applications.

No External Capacitor Needed:

The model from this series operates stably without the need for an external output capacitor, simplifying design and reducing component count.

Fixed and Adjustable Voltage Options:

It comes in both fixed (1.225V) and adjustable versions, giving you flexibility in voltage reference selection.

Low Output Noise:

With a low output noise of 20 µV rms (10 Hz to 10 kHz), the LM4041 ensures stable, clean voltage references, ideal for sensitive circuits.

High Accuracy and Low-Temperature Drift:

It offers excellent accuracy (±0.1% at 25°C for A-grade) and a low-temperature coefficient of 100 ppm/°C, ensuring consistent performance across different temperatures.
