Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB confirms lead-free compliance and RoHS adherence. Confirm the 'M' designation indicates the SOIC-8 surface-mount package variant rather than through-hole options. Ensure the specific revision matches design requirements for thermal performance and pin compatibility during sourcing.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required with moderate current demands up to 500mA. It is suitable for designs prioritizing simplicity over adjustable voltage flexibility. Consider the SOIC-8 footprint constraints and thermal dissipation capabilities relative to the expected load current and ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 series of SIMPLE SWITCHER converters, designed for high-efficiency step-down applications.
