LM2750SD-5.0 Equivalent & Substitute Parts

Part Overview

The LM2750SD-5.0 is a charge pump switching regulator IC manufactured by Texas Instruments, designed to provide a fixed 5V output with 120mA current capacity. This device operates as a step-up converter using charge pump topology, accepting input voltages between 2.7V and 5.6V. The component is classified as obsolete, which necessitates identification of equivalent alternatives for ongoing design support and procurement continuity. The LM2750SD-5.0/NOPB variant provides direct functional equivalence with active product status.

Substitute Part Grouping Explanation

Substitution eligibility for the LM2750SD-5.0 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage: 5V
• Output current capacity: 120mA
• Input voltage range: 2.7V to 5.6V
• Switching frequency: 1.7MHz
• Topology: Charge pump step-up converter
• Package: 10-WFDFN Exposed Pad (10-WSON 3x3)
• Operating temperature range: -40°C to 125°C
• Mounting type: Surface Mount

The LM2750SD-5.0/NOPB variant meets all substitution criteria as a direct equivalent. This part maintains identical electrical specifications and physical packaging while offering active product status, enabling continued procurement and design support.

Parameter Comparison

Engineering Selection Recommendations

The LM2750SD-5.0/NOPB is the direct substitute for the obsolete LM2750SD-5.0. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction is product status: the LM2750SD-5.0/NOPB maintains active availability, eliminating procurement risk associated with obsolete components. Both parts carry identical export classification (EAR99) and tariff codes (8542.39.0001), with no compliance or regulatory differences. Selection of the LM2750SD-5.0/NOPB is appropriate for new designs and ongoing production requiring charge pump regulation at 5V with 120mA output capacity in the 10-WSON package.

Frequently Asked Questions (FAQ)

Q: Can the LM2750SD-5.0/NOPB be used as a direct replacement for the LM2750SD-5.0?

A: Yes. Both parts are electrically and mechanically identical. The LM2750SD-5.0/NOPB provides the same 5V fixed output, 120mA current capacity, input voltage range of 2.7V to 5.6V, and 10-WFDFN package configuration. The primary difference is active product status for the /NOPB variant.

Q: What does the /NOPB suffix indicate?

A: The /NOPB designation indicates "No Plumbum" (lead-free) packaging. This is a standard industry suffix denoting RoHS compliance in the packaging format.

Q: Are there any differences in operating temperature range between these parts?

A: No. Both the LM2750SD-5.0 and LM2750SD-5.0/NOPB operate across the identical temperature range of -40°C to 125°C (TA).

Q: Can this charge pump regulator be used in applications requiring higher output current?

A: No. The LM2750SD-5.0 and LM2750SD-5.0/NOPB are rated for 120mA maximum output current. Applications requiring higher current capacity require alternative components with higher current specifications.

Q: Is the 10-WSON package compatible with standard surface mount assembly processes?

A: Yes. The 10-WFDFN Exposed Pad package (10-WSON 3x3) is a standard surface mount package compatible with conventional pick-and-place and reflow soldering processes.

Q: What is the minimum input voltage required for this regulator?

A: The minimum input voltage is 2.7V. Input voltages below this threshold will not produce the specified 5V output.
