Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575D2T-5R4

LM2575D2T-5R4

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575D2T-5R4 is a monolithic integrated circuit step-down switching regulator from the LM2575 series, manufactured by onsemi. It operates as a buck converter with a fixed 5V output and a maximum output current of 1A. The device supports an input voltage range from 4.75V to 40V and utilizes a 52kHz internal oscillator for regulation. It is housed in a TO-263-5 (D2PAK) surface-mount package and is rated for operation between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage power switch eliminates the need for external driver components
Fixed 52kHz internal oscillator simplifies design and reduces component count
Built-in thermal shutdown protects against overheating under fault conditions
Internal frequency compensation ensures stability without external phase adjustment

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load DC/DC conversion modules
Pre-regulator stages for linear post-regulators
Efficient battery-powered systems requiring step-down topology

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'R4' against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with standard D2PAK footprints during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a simple, cost-effective buck converter solution with fixed 5V output. Consider the TO-263 package for adequate thermal dissipation at full load. Verify that the 52kHz switching frequency aligns with electromagnetic interference requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of adjustable and fixed-output regulators. The 'D2T' designation indicates the surface-mount D2PAK package variant, while '5R4' specifies the 5V fixed output version in reel packaging. It serves as a direct replacement for legacy through-hole versions in modern compact designs.
