LM2575M-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575M-5.0/NOPB is a monolithic integrated circuit step-down switching voltage regulator from Texas Instruments, designed for high-efficiency power conversion. It operates with an input voltage range of 4 V to 40 V and provides a fixed 5.0 V output capable of driving up to 1 A load current. The device utilizes a fixed 52 kHz internal oscillator to minimize external component requirements while maintaining excellent line and load regulation. Packaged in an 8-pin SOIC surface-mount format, it integrates essential protection features including thermal shutdown and cycle-by-cycle current limiting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated fixed-frequency oscillator eliminates the need for external timing components
Built-in thermal shutdown and cycle-by-cycle current limiting ensure operational safety under fault conditions
Designed as a direct replacement for three-terminal linear regulators to reduce heat dissipation requirements

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load DC/DC conversion modules
Pre-regulator stages for switching regulators
Efficient buck converters for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the package designation matches the required 8-pin SOIC footprint for PCB layout compatibility. Ensure the fixed 5.0 V output variant aligns with system voltage requirements, as other voltage options exist within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required with a maximum load current of 1 A. The SOIC package is suitable for applications prioritizing surface-mount assembly over through-hole mounting. Consider the 52 kHz switching frequency for balancing electromagnetic interference filtering needs against passive component size constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of simple switchers, which are widely recognized for their ease of use and minimal external component count. The 'M' suffix denotes the surface-mount SOIC package, distinguishing it from through-hole variants like the TO-220 or TO-263 packages found in other members of the series.
