Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'BN' corresponds to the PDIP-8 package and 3.3V fixed output variant. Confirm RoHS compliance status as some legacy listings may indicate non-compliance. Check manufacturer documentation for lead-free availability and ensure the part number matches the required pinout configuration for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from an input source between 4V and 40V. Ensure the load current does not exceed 500mA continuous operation. Consider thermal management requirements given the through-hole packaging and power dissipation characteristics under heavy loads or high input-output differentials.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574 series of simple switcher regulators. The 'BN' suffix typically denotes the PDIP-8 package and a specific fixed output voltage. The series is known for reducing design time and complexity in switching power supply applications compared to discrete solutions.
