LM4051BEM3-1.2 Description

Short technical summary and product information.

The LM4051BEM3-1.2 by NS is a precision micropower shunt voltage reference designed for space-critical applications. It is available in a sub-miniature SOT-23 surface mount package.

 

Key electrical specifications include an output voltage tolerance of ±0.1% at 25°C, an output noise of 20µVrms (10Hz to 10kHz), and a temperature coefficient of 50ppm/°C maximum. The device operates over a current range of 60µA to 12mA and has an operating temperature range of -40°C to 125°C.

 

The advanced design of the LM4051-N eliminates the need for an external stabilizing capacitor, maintaining stability with any capacitive load. This simplifies design efforts, along with the availability of a fixed 1.225V reverse breakdown voltage option. The part is suitable for industrial and extended temperature range applications.

 

Packaged in a 3-pin SOT-23 (DBZ) package, the LM4051BEM3-1.2 is designed for surface mounting. The standard package quantity is 3,000 units on tape and reel.
