Procurement Notes
Verify the specific suffix EN against the official Diotec Semiconductor datasheet to confirm compliance with RoHS3 standards and REACH regulations. Ensure that the ordering information matches the exact electrical parameters required for the target application circuit. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement decisions.
Selection Notes
Select this component when a compact SOT-23-5 footprint is required alongside a 500mA output capability. Consider the 18V maximum input rating and 3.6µA static current for low-power designs. Evaluate the thermal performance characteristics relative to the expected ambient temperature and PCB copper area to ensure reliable operation within the specified -40°C to +125°C junction temperature range without exceeding safety margins.
