## Summary description

The Texas Instruments LM2574 M5.0 is a fixed 5 V step-down (buck) regulator in an SO-14 package. Designed for DC–DC voltage conversion with an input range of 4–40 V, it provides a stable 5 V output for powering electronic circuits and modules. Suitable for embedded systems, power supplies, and battery-powered applications requiring regulated 5 V rail and compact through-hole/SO-14 mounting.

## Long description

The Texas Instruments LM2574 M5.0 is a fixed 5 V step-down (buck) switching regulator in an SO-14 through-hole package. Designed for DC–DC voltage conversion, it accepts a wide input range from 4 V to 40 V and delivers a regulated 5 V output suitable for powering microcontrollers, sensors, and other 5 V electronics. The device integrates the switching element and control circuitry to provide efficient voltage regulation with a compact footprint for board-level applications and power-supply designs.
Advantages
The LM2574 M5.0 provides a stable fixed 5 V output with a broad input voltage range, enabling use with various power sources including batteries and higher-voltage rails. Its integrated switching regulator architecture reduces external component count and board space compared with discrete linear regulators. The SO-14 package supports through-hole mounting for prototyping and repairability, while the regulator’s design emphasizes efficiency at typical load currents, reducing heat dissipation in many applications.
Suitable for
Embedded systems and microcontroller power rails requiring a regulated 5 V supply
Battery-powered devices and portable equipment with input voltages up to 40 V
Power-supply modules and industrial control electronics
Repair, prototyping, and board-level designs using SO-14 through-hole components
Key specifications
Function: Step-down (buck) switching regulator with fixed 5 V output
Input voltage range: 4 V to 40 V
Output voltage: Fixed 5.0 V
Package type: SO-14 through-hole package
Integrated switching and control circuitry for reduced external components
How to use
Install the SO-14 device on a PCB following recommended footprint and pin connections for input, output, ground, and switch node. Use appropriate input and output decoupling capacitors and the inductor, catch diode, and output capacitor values recommended by the manufacturer to ensure stable regulation and low ripple. Observe proper thermal layout and keep high-current traces short. Verify the input voltage remains within the 4–40 V range and confirm output regulation under expected load conditions before connecting sensitive circuitry.
Usage recommendations
For reliable operation, follow the manufacturer’s application notes for component selection (inductor, diode, capacitors) and layout to minimize noise and ensure stable regulation. Ensure adequate heat dissipation for continuous loads near the regulator’s limits and include input surge protection if supply sources can produce transients above 40 V.
