Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm exact electrical tolerances and temperature grades. Ensure compatibility with your PCB footprint for the VSON-EP-10 package. Cross-reference the datasheet revision date to validate pinout and thermal pad specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a wide input range up to 65V. It is appropriate for designs prioritizing low static power consumption over high current delivery. Consider alternative parts if output currents exceeding 150mA are necessary or if adjustable output voltages are preferred over fixed configurations.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5165 family of synchronous buck converters. The family is characterized by high input voltage capabilities and integrated power switches. The XDRCR variant specifically denotes the fixed 5V output version in a reel-packaged VSON-EP-10 form factor, targeting cost-sensitive and space-efficient power management solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM5165YDRCR offers a fixed 3.3V output instead of 5V. LM5165DRCR provides an adjustable output voltage range rather than a fixed 5V rail. Verify pinout compatibility and thermal characteristics when substituting these variants.
