• Designed for low power consumption applications
• Suitable for compact surface-mount designs

Voltage Reference Applications

• Portable instrumentation systems
• Battery-powered measurement devices
• Data acquisition circuits

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and confirms RoHS compliance as per manufacturer documentation. Ensure the ordering part number matches the required tolerance and package variant exactly, as minor suffix changes may affect specifications or availability. Confirm end-of-life status if applicable.

Voltage Reference Selection Notes

Select this component when a 10 V reference with ±0.1% accuracy is required in a small SOT-23-3 footprint. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Verify that the 15 mA maximum shunt current meets the circuit's biasing requirements without exceeding power dissipation limits.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The LM4050AEM3-10/NOPB specifically denotes the 10 V version with A-grade accuracy in the EM3 (SOT-23) package.
