## Summary description

LM2574 M-ADJ is a Texas Instruments step-down (buck) switching regulator in SO-14 package with adjustable output. It accepts input voltages from 4 to 40 V and provides an adjustable output range of 1.2 to 37 V. Designed for DC–DC conversion, the IC suits power-supply designs for embedded systems, industrial electronics and battery-powered devices requiring regulated stepped-down voltages.

## Long description

The LM2574 M-ADJ from Texas Instruments is a step-down (buck) switching regulator in an SO-14 package with an adjustable output. It accepts input voltages from 4 V to 40 V and provides an adjustable output within the range of 1.2 V to 37 V. The device is intended for DC–DC conversion tasks where a compact, efficient regulator with adjustable output is required, including in embedded systems, industrial electronics and battery-powered equipment.
Advantages
The regulator offers wide input and output ranges enabling flexible use across multiple applications. Its switching architecture improves conversion efficiency compared with linear regulators, reducing heat dissipation and allowing smaller external components. The SO-14 package supports through-hole or hybrid PCB mounting and facilitates straightforward board-level integration. The adjustable output lets designers set the required regulated voltage without needing multiple fixed-voltage parts.
Suitable for
 Embedded system power supplies and microcontroller boards
 Industrial control modules and instrumentation
 Battery-powered devices and portable equipment
 Power rails that require adjustable regulated voltages for sensors or actuators
Key specifications
 Input voltage range: 4 V to 40 V
 Adjustable output voltage range: 1.2 V to 37 V
 Topology: Step-down (buck) switching regulator
 Package type: SO-14
 Intended use: DC–DC conversion for regulated outputs
How to use
Install the LM2574 M-ADJ on the PCB following recommended footprint and pin connections for the SO-14 package. Provide input decoupling and an appropriately rated inductor and output capacitor as specified in the device application notes to ensure stable regulation and low output ripple. Use the external resistor network on the feedback pin to set the desired output voltage within the 1.2 V to 37 V range, and add any required compensation or snubber components per design guidelines. Ensure the input source can supply sufficient current for the load plus switching losses and that thermal considerations are addressed via PCB copper areas or a heatsink if necessary.
Usage recommendations
Follow Texas Instruments' published application circuits and layout recommendations to minimize switching noise and ensure reliable operation. Choose components (inductor, diode, capacitors) that meet the current and voltage ratings for the intended load and operating conditions, and verify thermal performance under maximum load to prevent overheating.
