Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MH' corresponds to the HTSSOP-20 package and tube packaging format as listed in official documentation. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance status. Ensure the component matches the standard commercial grade specifications rather than automotive variants like the Q-series. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 42 V is required alongside a 2.5 A load capability. The fixed 1 MHz frequency is suitable for designs prioritizing small passive component size. Consider the HTSSOP-20 package for applications requiring adequate thermal dissipation without excessive board space. This regulator is appropriate for systems needing adjustable output voltages between 800 mV and 7 V with high efficiency requirements.
