Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized channels as the part status is End-of-Life. Confirm RoHS compliance requirements against specific project standards, noting that some listings indicate non-compliance. Validate package integrity upon receipt due to the thin SOT-23-5 form factor. Ensure supply chain partners provide valid traceability documentation for quality assurance purposes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from a low-voltage source. It is suitable for designs needing minimal external components and compact footprint. Consider alternative models within the NCP1400A series if different output voltages or active status parts are necessary for long-term production.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the NCP1400A family of micro-power boost converters. The series was introduced to address power management needs in portable devices. While many variants remain active, this specific fixed-output version has reached end-of-life status, limiting its availability for new designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for active equivalents in the NCP1400A series with compatible output voltages. Verify pin compatibility and electrical specifications before substitution.
