Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Y' indicates the fixed 3.3V output variant when ordering. Confirm the 'DRCT' suffix corresponds to the tape-and-reel packaging format. Ensure compatibility with the 10-VSON-EP-10 footprint during PCB layout. Check for RoHS compliance status as per the manufacturer's latest documentation before final procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a fixed 3.3V output from inputs up to 65V. The 150mA current limit suits low-power loads. Consider the 600kHz switching frequency for smaller passive components. The wide temperature range supports industrial or automotive environments if qualified. Verify thermal dissipation requirements for the small VSON package under load.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5165 family of synchronous buck converters. It shares core architecture with variants like LM5165XDRCT but differs in output configuration. The 'Y' suffix specifically denotes the fixed 3.3V output option, distinguishing it from adjustable or other fixed voltage versions within the same series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM5165XDRCT offers similar specifications but may have different output voltage configurations. Verify pinout and electrical parameters match exactly before substitution. Other LM5165 variants share the same package but require confirmation of output voltage and current ratings.
