Procurement Notes
Verify the specific suffix TE1 indicates tape and reel packaging when ordering. Confirm the manufacturer designation as Nisshinbo Micro Devices Inc., resulting from the merger of New Japan Radio and Ricoh Micro Devices. Ensure compatibility with standard SOT-23-5 footprints during procurement planning.
Selection Notes
Select this component when an adjustable shunt regulator is required within the 1.25V to 13V range. Consider the 30mA maximum current rating for load requirements. Evaluate the SOT-23-5 package constraints against available board space. Compare temperature coefficients against application thermal profiles to ensure long-term accuracy.
Part Context
This part belongs to the NJM282x series of precision voltage references from Nisshinbo Micro Devices. The series includes variants like the NJM2825F-TE1, which offers fixed reference options. These components are designed for general-purpose analog applications where stable, adjustable voltage references are critical for system performance and accuracy.
Replacement Considerations
Check datasheets for compatible adjustable shunt regulators with similar voltage ranges and current capabilities. Verify pinout compatibility for direct replacement in existing designs. Ensure thermal characteristics and package dimensions match the original footprint requirements.
