Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575MX-5.0/NOPB

LM2575MX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575MX-5.0/NOPB is a step-down switching voltage regulator manufactured by Texas Instruments, continuing the legacy of the National Semiconductor LM2575 series. It operates with an input voltage range of 4.75 V to 40 V and provides a fixed 5.0 V output at up to 1 A load current. The device utilizes a buck topology with a typical switching frequency of 52 kHz. It is housed in an 8-pin SOIC surface-mount package (TO-263 equivalent footprint) and supports operation from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic power switch rated for 1 A continuous output current
Fixed internal feedback network ensures precise 5.0 V output regulation
Built-in thermal shutdown and current limit protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load DC/DC conversion modules
Pre-regulator stages for linear regulators
Battery-powered systems requiring efficient step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the ordering suffix /NOPB confirms lead-free and RoHS compliance status as per the manufacturer's datasheet. Confirm the package designation matches the required 8-pin SOIC form factor. Ensure the part number corresponds to the fixed 5.0 V output variant rather than adjustable or other voltage options within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact surface-mount solution is required for 1 A step-down applications. The fixed 5.0 V output eliminates external resistor networks, simplifying design. Consider the 52 kHz switching frequency for balancing component size and efficiency against noise sensitivity requirements in the target circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 SIMPLE SWITCHER® power converter family, originally developed by National Semiconductor and now produced by Texas Instruments. The 'MX' suffix indicates the SOIC surface-mount package, while '/NOPB' denotes non-halogenated and lead-free construction. It serves as a direct pin-compatible replacement for older National Semiconductor versions.
