LM2675M-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675M-ADJ/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator in an SOIC-8 package. It operates with an input voltage range of 6.5V to 40V and delivers up to 1A output current. The adjustable output voltage spans from 1.21V to 37V. Key electrical parameters include a switching frequency of 260kHz, typical efficiency of 90%, and quiescent current of 2.5mA. It functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic power switch eliminates the need for external components typically required in discrete designs.
• Fixed internal switching frequency simplifies external component selection and reduces overall solution size.
• Built-in thermal shutdown and current limit protection ensure robust operation under fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient step-down conversion
• Industrial control systems operating in harsh environments

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Choose this component when a fixed 260kHz frequency and 1A current capacity suit the design. It is suitable for applications requiring an input voltage up to 40V. Consider alternative packages like LD or N if through-hole or smaller surface-mount footprints are necessary for the specific board layout constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2675 series of SIMPLE SWITCHER regulators. It shares functional similarities with the LM2675N (through-hole) and LM2675LD (WSON) variants. The M suffix specifically denotes the SOIC-8 surface-mount package configuration used in this part number.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2675M-5.0/NOPB offers a fixed 5V output instead of adjustable voltage. LM2675N-ADJ/NOPB provides the same functionality in a PDIP package. Verify pinout compatibility and thermal performance when substituting these related part numbers.
