Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and check for any active Product Change Notifications (PCNs) that may affect material composition or manufacturing location before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an ultra-low start-up voltage is required from a single energy source. The 2A switch current rating suits moderate power loads, while the 2MHz frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context
