• Fixed 2.5 V output voltage configuration
• Integrated power switches for compact design

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered portable devices
• Industrial control power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance as per Texas Instruments standards. Ensure the 'MTC' designation matches the required 16-pin TSSOP package for your PCB layout. Confirm the '-2.5' variant provides the specific fixed voltage needed, rather than the adjustable version.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 V rail is required at up to 1.5 A. It is suitable for applications needing high efficiency over a wide load range. Compare against the adjustable LM2651MTC-ADJ/NOPB if variable output is preferred. Consider the LM2655 series for higher current demands exceeding 1.5 A.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM265x family of high-efficiency synchronous buck regulators. It shares architectural similarities with the LM2655 but offers lower current capacity. The family is designed for space-constrained applications requiring robust performance across industrial temperature ranges.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2651MTCX-2.5/NOPB is the tape-and-reel equivalent of the tube-packaged LM2651MTC-2.5/NOPB. Both share identical electrical specifications and pinouts.
