LM4050CEM3-5.0 T_LF

5.0 V Precision Shunt Voltage Reference with Low Temperature Drift

Product Description

Product Overview

The LM4050CEM3-5.0 T_LF is a high-precision micropower shunt voltage reference that provides a stable 5.000 V reference output with low temperature coefficient and low noise. It is designed to operate over a wide range of shunt currents with minimal external components and does not require an output capacitor for stability, even with capacitive loads. Its compact SOT-23-3 package makes it ideal for space-constrained applications in precision measurement, power management, and analog signal conditioning.
