LM4050CEM3X-8.2/NOPB

Voltage Reference Overview

The LM4050CEM3X-8.2/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring an 8.192 V fixed reverse breakdown voltage with a ±0.5% initial accuracy at 25°C. It operates within a wide current range of 74 μA to 15 mA and maintains a low temperature coefficient of 50 ppm/°C maximum across the extended industrial temperature range of -40°C to +125°C. The device utilizes a compact SOT-23 surface-mount package (DBZ) measuring approximately 3 mm by 1.3 mm. Designed for stability without external components, it tolerates capacitive loads directly, eliminating the need for output stabilization capacitors.

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and confirms the C-grade tolerance level. Ensure the ordering code matches the required 8.192 V output option. Confirm the DBZ package variant aligns with PCB footprint requirements. Cross-reference the datasheet revision date against manufacturing lot specifications to ensure consistency with current production standards.

Voltage Reference Selection Notes

Select this component when a fixed 8.192 V reference is required in a minimal footprint. The C-grade offers standard precision suitable for general-purpose applications. Consider the minimum operating current of 74 μA for low-power designs. Evaluate thermal resistance parameters if high ambient temperatures are expected. Verify that the load current remains within the specified 15 mA maximum limit during operation.
