Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HVM' corresponds to the SOIC-8 package and 500 mA rating. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the ordering part number matches the required thermal performance and pinout for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from high-voltage inputs up to 60 V. The 150 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 500 mA load requirement does not exceed the device's thermal limits in your specific enclosure design.

Voltage Regulators - DC DC Switching Regulators Part Context
