Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2574MX-5.0/NOPB

LM2574MX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2574MX-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER® step-down voltage regulator in a 14-pin SOIC package. It provides a fixed 5V output with a maximum current of 500mA. The device operates from an input voltage range of 4V to 40V at a typical switching frequency of 52kHz. Internal features include a 150mA standby current and thermal shutdown protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage power switch for simplified circuit design
Fixed internal feedback network ensures stable regulated output
Thermal shutdown protection prevents damage during overload conditions

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation modules
Pre-regulators for switching regulators
Efficient buck converters for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB indicates lead-free compliance and RoHS adherence. Confirm the MX suffix corresponds to the SOIC-14 tape-and-reel packaging format. Ensure the -5.0 designation matches the required 5V fixed output voltage specification for your application.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from an input voltage up to 40V. The 500mA current rating suits moderate load applications. Consider the 52kHz switching frequency for standard passive component sizing. Verify that the SOIC-14 package fits the available PCB footprint constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574 family of SIMPLE SWITCHER regulators, designed for ease of use with minimal external components. It serves as a drop-in replacement for older linear regulators in many applications, offering higher efficiency by operating in a switching mode rather than dissipating excess voltage as heat.
