Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' indicates lead-free and RoHS compliance. Confirm the 'M' suffix corresponds to the SOIC-8 package variant. Ensure the 'ADJ' designation matches the requirement for adjustable output rather than fixed voltage options. Cross-reference the manufacturer part number with official datasheets to validate pinout and electrical specifications before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60 V is required with moderate output current capabilities. The fixed 150 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the SOIC-8 package for space-constrained surface-mount designs. Verify that the thermal performance of the PCB layout supports the expected load conditions within the specified operating temperature range.
