LM4040AIM3X-2.5 Description

Short technical summary and product information.

The LM4040-N series from Texas Instruments is a precision micropower shunt voltage reference designed for space-critical applications. This specific part, the LM4040AIM3X-2.5, offers a fixed reverse breakdown voltage of 2.5V with a tight tolerance of ±0.1% at 25°C.

 

It features a wide operating current range from 60µA to 15mA and a low temperature coefficient of 100ppm/°C maximum. The device operates across industrial and extended temperature ranges, from -40°C to +85°C and -40°C to +125°C, respectively. It does not require an output capacitor and tolerates capacitive loads.

 

The LM4040AIM3X-2.5 is supplied in a small SOT-23 package, making it suitable for designs where space is limited. Its key specifications include low output noise of 35µVrms (typical) between 10Hz and 10kHz.

 

This voltage reference is ideal for various power management applications requiring a stable and accurate voltage reference. Its small footprint and robust performance characteristics make it a versatile component for embedded systems and portable electronics.
