LM22675MRE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22675MRE-5.0/NOPB is a fixed-output step-down switching voltage regulator from Texas Instruments' SIMPLE SWITCHER family. It integrates a high-side N-channel MOSFET to deliver up to 1A of load current with a fixed 5V output. The device operates within an input voltage range of 4.5V to 42V and supports a switching frequency of 500kHz. It features ±1.5% feedback reference accuracy, internal compensation for stability with low ESR capacitors, and a precision enable pin. The component functions across a junction temperature range of -40°C to +125°C and is housed in an 8-SO PowerPAD package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and RoHS status. Ensure the specific package variant (SO-PowerPAD-8) matches the PCB footprint requirements. Confirm that the fixed 5V output specification aligns with the target circuit design needs before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from an input voltage ranging between 4.5V and 42V. It is suitable for designs needing up to 1A continuous load current without external compensation components. Consider the 8-SO PowerPAD package for thermal management and space-constrained applications requiring surface mount installation.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the LM2267x series of SIMPLE SWITCHER products, which are designed to minimize external component count. The LM22675 variant specifically targets 1A applications, distinguishing it from the higher current LM22673 and lower current LM22671 models within the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22675MRX-5.0/NOPB offers the same electrical specifications in a tape-and-reel packaging format instead of cut tape.
