Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'M' indicates tape-and-reel packaging versus tube packaging when sourcing. Confirm RoHS compliance status via the manufacturer's official datasheet or certification documents. Ensure the ordering part number matches the required output voltage variant exactly. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and supply chain integrity before purchase.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a fixed 3.3 V output from higher input voltages up to 60 V. The 500 mA output current rating suits moderate load applications. Consider the SOIC-8 package for surface-mount assembly constraints. Evaluate the 150 kHz switching frequency against electromagnetic interference requirements and passive component size limitations in the target design.
