Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CS' against the official Taiwan Semiconductor datasheet to confirm package dimensions and thermal characteristics. Ensure compatibility with RoHS3 standards as indicated in public documentation. Confirm that the 8-SOP footprint matches the target PCB layout requirements before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output adjustable regulator is required within a 3V to 40V input range. It is suitable for designs prioritizing minimal external component count. Consider the 1.5A switch current limit when sizing external inductors and diodes. Verify that the operating temperature range meets the environmental constraints of the intended application.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TS34063 family of switching regulators, which are direct functional equivalents to the industry-standard MC34063 series. The TS34063CS variant specifically denotes the SOP-8 surface-mount package configuration offered by Taiwan Semiconductor, maintaining the same internal architecture as through-hole versions while adapting to modern assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitute part numbers include MC34063AD (Texas Instruments) and MC34063ADR2G (onsemi). These alternatives share identical pinouts and core electrical specifications but may differ in package type or commercial availability status.
