Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CQ' against official Analog Devices documentation to confirm it denotes the commercial grade and lead-free (PBF) status. Ensure the TO-220-5 package matches your thermal and mechanical requirements. Cross-reference the datasheet for any recent product change notices that may affect specifications or availability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a higher input voltage up to 60V. It is suitable for applications needing a robust bipolar regulator with integrated protection. Consider the 100kHz switching frequency for passive component sizing. Verify that the through-hole TO-220-5 package fits the assembly constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1076 series of high-performance switching regulators. The LT1076 family is known for its ability to operate in various topologies including buck, boost, and flyback. The '-5' suffix indicates a fixed 5V output version, while the '#PBF' signifies a lead-free finish compliant with RoHS standards.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1076CT-5#PBF: Same electrical specifications but in a TO-220-5 through-hole package instead of the potentially different package implied by CQ if not standard. LT1076CR-5#PBF: Same electrical specifications but in a DDPAK-7 surface-mount package.
