Frequently Asked Questions (FAQ)

Q: Can the LM2750LD-5.0/NOPB be used as a direct replacement for the LM2750LD-5.0?

A: Yes. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, output voltage (5V), output current (120mA), input voltage range (2.7V to 5.6V), switching frequency (1.7MHz), and package configuration (10-WFDFN Exposed Pad). No circuit modifications are required.

Q: What is the difference between the LM2750LD-5.0 and LM2750LD-5.0/NOPB?

A: The primary differences are product status and compliance certifications. The LM2750LD-5.0/NOPB is an active product with ROHS3 compliance, while the LM2750LD-5.0 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the 10-WFDFN Exposed Pad package in 10-WSON (3x3) configuration with surface mount mounting type. PCB layout and assembly processes remain unchanged.

Q: What is the Moisture Sensitivity Level (MSL) difference, and does it affect compatibility?

A: The LM2750LD-5.0 has MSL 1 (Unlimited), while the LM2750LD-5.0/NOPB has MSL 3 (168 Hours). This affects storage and handling procedures but does not impact electrical performance or functional compatibility in the application.

Q: Is the LM2750LD-5.0/NOPB available in the same packaging options?

A: The LM2750LD-5.0/NOPB is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.
