LM4050QML-SP (ACTIVE)

Precision Micropower Shunt Voltage Reference

 

Description

The LM4050QML precision voltage reference is available in a 10-Lead Ceramic CLGA package. The LM4050QML’s design eliminates the need for an external stabilizing capacitor while ensuring stability with a capacitive load, thus making the LM4050QML easy to use. The LM4050-2.5QML has a 60 µA minimum and 15 mA maximum operating current. The LM4050-5.0QML has a 74 µA minimum and 15 mA maximum operating current.

The LM4050QML utilizes fuse and zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1% at 25°C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.

The LM4050QML operates over the temperature range of –55°C to +125°C.
