LM22671MR-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22671MR-5.0/NOPB is a fixed-output buck switching regulator from Texas Instruments' SIMPLE SWITCHER family, housed in an SO-PowerPAD-8 package. It provides a fixed 5 V output with a maximum current of 500 mA. The device operates within an input voltage range of 4.5 V to 42 V and supports a switching frequency up to 1 MHz. It functions reliably across an extended temperature range from -40 °C to +125 °C, featuring a typical quiescent current of 3.4 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Wide input voltage range accommodates various supply sources
• Thermal shutdown and current limit protection included

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Industrial control power supplies
• Telecommunications equipment
• Battery-powered devices requiring stable 5 V rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance as per manufacturer specifications. Confirm the SO-PowerPAD-8 package type matches your PCB footprint requirements. Ensure the fixed 5 V output aligns with your system voltage needs, as adjustable variants exist within the same series. Check datasheet for thermal pad soldering guidelines to ensure proper heat dissipation during operation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required with moderate current demands up to 500 mA. It is suitable for designs needing a wide input voltage range up to 42 V. Consider the SO-PowerPAD-8 package for its thermal performance and compact size. Compare with adjustable versions if variable output voltages are needed instead of the fixed 5 V option.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22671 series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM22671MR-ADJ but offers a fixed output. The series is designed for cost-sensitive applications requiring reliable DC-DC conversion without external feedback resistors for voltage setting.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22671MR-5.0 is the non-RoHS equivalent. LM22671MRX-5.0/NOPB offers the same electrical characteristics in a tape-and-reel package instead of tube packaging.
