LM2575S-5.0-EV

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575S-5.0-EV is a fixed-output step-down switching regulator manufactured by EVVO, belonging to the LM2575 series. It provides a regulated 5.0V output with a maximum load current of 3A. The device operates from an input voltage range up to 40V and utilizes a 150kHz internal oscillator frequency for efficient DC-DC conversion. Housed in a TO-263-5L surface-mount package, it integrates thermal protection and current limiting features suitable for industrial applications operating between -40°C and 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as EVVO rather than Texas Instruments, as this indicates a compatible or alternative source part. Confirm the suffix 'EV' corresponds to the specific packaging and environmental compliance status required for your assembly process. Ensure the TO-263-5L footprint matches your PCB design guidelines before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V rail is required with up to 3A capacity from inputs up to 40V. The 150kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the TO-263-5L package for its thermal performance in space-constrained designs without requiring additional heatsinking under moderate loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the LM2575 family of SIMPLE SWITCHER devices, known for their ease of use and robust performance in step-down applications. The EVVO variant maintains functional compatibility with industry-standard pinouts while offering localized supply chain options. It serves as a direct replacement for legacy linear regulators in systems requiring higher efficiency and reduced heat dissipation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2575S-5.0 from Texas Instruments or equivalent parts from National Semiconductor. Verify pinout compatibility and thermal characteristics when transitioning between manufacturers to ensure reliable operation in existing designs.
