High precision with 0.1% initial accuracy and low noise
Stable operation without external stabilizing capacitors
Capable of tolerating any capacitive load

Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process controls
Automotive systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, temperature range, and compliance status. Confirm that the requested part number matches the exact electrical specifications required for the design. Ensure compatibility with the intended manufacturing processes and environmental operating conditions before finalizing procurement.

Selection Notes

Select this component when high precision and minimal board space are critical requirements. The SC70 package offers a significant size reduction compared to standard SOT23 packages. Verify that the application circuit maintains the shunt current within the specified operational limits to ensure stable voltage regulation across the full temperature range.

Part Context

This component belongs to the LM4040 series of improved precision micropower shunt voltage references. The series includes multiple fixed reverse-breakdown voltages and various accuracy grades. The 'A' designation indicates the highest accuracy grade of 0.1%, while the 'E' suffix specifies the extended industrial temperature range capability up to +125°C.
