Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance as per manufacturer specifications. Confirm the SOIC-8 package variant matches your PCB footprint requirements. Ensure the fixed 12 V output aligns with your system design needs, as adjustable versions exist within the same series. Cross-reference the datasheet for specific ordering information and environmental certifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required with moderate current demands up to 500 mA. The wide input voltage range suits applications with varying supply sources. Consider the SOIC-8 package for space-constrained designs. Compare against adjustable variants if flexible output voltages are needed instead of a fixed setting.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2597HV series of SIMPLE SWITCHER power converters. It is designed for high-efficiency step-down applications.
