Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' against the official manufacturer datasheet to confirm package type and tape-and-reel availability, as standard 'S' variants may differ in packaging configuration. Ensure compatibility with RoHS and REACH regulations required for your region. Cross-reference the full part number with authorized distributors to confirm current production status and lead times.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from a wide input voltage range up to 40 V. It serves as a direct replacement for linear regulators to improve efficiency and reduce heat dissipation needs. Consider the TO-263-5 package for adequate thermal performance without additional heatsinks in moderate load applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2575 series of SIMPLE SWITCHER power converters, designed to provide all active functions for a complete step-down (buck) switching regulator. The series offers fixed output voltages of 3.3V, 5V, 12V, and 15V, alongside adjustable versions, enabling easy design implementation with minimal external components.
