LA5752-E-SY

Voltage Regulators - DC DC Switching Regulators Overview

The LA5752-E-SY is a monolithic linear integrated circuit functioning as a separately-excited step-down switching regulator. It provides a fixed positive output voltage of 5V with a single output channel. The device operates within an input voltage range of 7V to 28V and utilizes a TO-220-5 package for through-hole mounting. It features a switching frequency of 60kHz and supports an operating junction temperature range from -30°C to 150°C. The component does not include a synchronous rectifier.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'E-SY' against manufacturer documentation to confirm lead-free and RoHS compliance status. Ensure the TO-220-5 package variant matches the required thermal and mechanical constraints for the target application. Cross-reference the 60kHz switching frequency requirement with system noise specifications before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from an input range of 7V to 28V. The TO-220-5 package is suitable for applications requiring robust thermal dissipation via through-hole mounting. Consider the non-synchronous rectifier topology when evaluating efficiency requirements at light loads compared to modern synchronous alternatives.
