Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the fixed output voltage variant matches the system design needs, as this part number specifies fixed 5V or 12V options rather than adjustable configurations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs prioritizing low component count and versatility in topology. It is suitable for applications where space is constrained but multiple conversion types are needed. Consider the 800mA current limit and 63kHz switching frequency when designing passive components. Verify thermal performance within the specified commercial temperature range for reliable operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1107 series of micropower DC/DC converters from Analog Devices. The series is known for its flexibility in providing positive, negative, or isolated outputs. The CS8 designation identifies the commercial temperature grade and surface-mount SOIC-8 packaging, distinguishing it from industrial grade or through-hole variants.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other parts within the LT1107 family such as LT1107IS8#PBF for extended temperature ranges. Cross-reference with similar micropower switching regulators if pin compatibility is not required. Ensure replacement parts support the same boost/buck/inverting functionality and output current capabilities.
