Procurement Notes
Verify the exact part number suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm that the component status aligns with production requirements, as availability may vary across distributors. Ensure compliance with environmental standards such as ECOPACK if applicable.
Selection Notes
Select this component for applications requiring a stable -15 V negative rail. Consider the D²PAK package for surface-mount designs where space efficiency is critical. Evaluate thermal management needs, as high output currents require sufficient heat dissipation to maintain performance within the specified operating temperature range.
Part Context
This component belongs to the L79xxC series of three-terminal negative regulators. The series offers various fixed output voltages including -5 V, -8 V, -12 V, and -15 V. It is designed to complement the L78xx positive regulator series, facilitating the creation of dual-polarity power supplies in standard electronic designs.
