LM2576S-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576S-5.0/NOPB is a Texas Instruments step-down switching regulator operating at a fixed 52 kHz frequency. It provides a fixed 5 V output with a maximum load current of 3 A. The device supports an input voltage range from 4 V to 40 V and utilizes a Buck topology. It is housed in a TO-263-5 (D2PAK) surface-mount package, rated for operation between -40 °C and +125 °C, and features a typical quiescent current of 5 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic power switch eliminates the need for external components
Fixed internal oscillator ensures stable 52 kHz switching frequency
Built-in thermal shutdown protects against overheating conditions

Voltage Regulators - DC DC Switching Regulators Applications

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

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS standards. Confirm the package designation matches the required TO-263-5 footprint. Ensure the input voltage requirements do not exceed the 40 V absolute maximum rating during transient events.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required with up to 3 A load capacity. It is suitable for designs prioritizing simplicity over adjustable output flexibility. Consider the TO-263-5 package for adequate thermal dissipation without requiring extensive heatsinking.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 family of SIMPLE SWITCHER regulators. It shares functional similarities with the through-hole LM2576T variant but offers a surface-mount form factor. It differs from the LM2596 series by utilizing a lower 52 kHz switching frequency compared to the 150 kHz standard.
