Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'WU-TR' confirms the TO-263-5 package and tape-and-reel shipping configuration. Ensure the manufacturer designation matches Microchip Technology, as legacy Texas Instruments versions may differ in pinout or thermal characteristics. Confirm RoHS compliance status for your assembly requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a wide input voltage range up to 40V. The TO-263-5 package provides superior thermal dissipation compared to smaller SOT packages, making it suitable for higher current applications. Consider the 52kHz switching frequency for balancing efficiency and external component size.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 family of simple-to-use step-down switching regulators. The '5.0' indicates the fixed 5V output variant, while 'WU' specifies the D2PAK (TO-263) surface-mount package. The '-TR' suffix denotes the reel packaging format for automated assembly processes.
