Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix CN8 indicates the PDIP-8 through-hole package variant. Confirm RoHS compliance status via the official datasheet. Ensure the fixed 5V output specification matches the design requirement, as other variants exist for different voltages or adjustable outputs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a wide input range. Consider the 63kHz switching frequency for EMI constraints. Compare against the IS8 surface-mount version if PCB space favors SMD over DIP packaging. Verify thermal performance for the intended load current.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1107 series of micropower DC/DC converters. It shares functional characteristics with other LT1107 variants but differs in package type (PDIP vs SOIC) and output configuration (Fixed 5V vs Adjustable). It serves as a legacy alternative to newer synchronous controllers.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1107CS8-5#PBF offers identical electrical specifications in an SOIC-8 surface-mount package. LT1107IS8#TRPBF provides adjustable output capability in an SOIC-8 package. Verify pin compatibility before substituting between package types.
