Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free compliance and exact electrical tolerances. Ensure the TO-263-5 package matches the PCB footprint requirements. Confirm that the fixed 12 V output aligns with the target application voltage needs before ordering.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a fixed 12 V output at 1 A is required from an input voltage up to 40 V. The TO-263-5 package is suitable for applications needing moderate thermal dissipation without complex heatsinking. Consider the adjustable variant if precise non-standard voltages are needed.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the LM2575 series of monolithic integrated circuits designed for step-down switching regulators. The 'S' suffix indicates the TO-263-5 surface-mount package, while '12' denotes the fixed 12 V output version. It is part of the SIMPLE SWITCHER family, emphasizing ease of use with minimal external components.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
LM2575S-12/NOPB is the direct lead-free equivalent. LM2575T-12/NOPB serves as a through-hole alternative in the TO-220-5 package.
