The Texas Instruments LM4050QML-SP is a space-graded precision voltage reference suitable for data acquisition systems, instrumentation, process control and energy management.

LM4050QML-SP is packaged in a 10-Lead Ceramic CLGA and is designed to operate without the need for an external stabilizing capacitor. LM4050QML-SP is also designed to ensure stability with a capacitive load.

Stable reverse breakdown voltage accuracy is ensured over a range of operating temperatures and currents through low dynamic impedance and bandgap reference temperature drift curvature correction.
