LM2750SD-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2750SD-5.0/NOPB is a fixed-output boost switched-capacitor voltage regulator manufactured by Texas Instruments, formerly National Semiconductor. It operates within an input voltage range of 2.7 V to 5.6 V and provides a regulated output of 5.0 V (typical), with a maximum output current of 120 mA. The device utilizes a WSON-10 package measuring 3 mm x 3 mm x 0.8 mm. Key electrical parameters include a switching frequency of 1.7 MHz, an efficiency of up to 87%, and a quiescent current of 5 mA. It functions across an operating temperature range of -40 °C to +85 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as the component was originally developed by National Semiconductor but is now produced and distributed by Texas Instruments following their acquisition. Ensure the suffix /NOPB confirms lead-free and RoHS compliance status according to current datasheets. Confirm the specific output voltage variant matches the system requirements, as other fixed voltages may exist within the same package family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductorless solutions are preferred to minimize PCB area and eliminate magnetic interference. It is suitable for applications where moderate output current up to 120 mA is sufficient and input voltages vary between 2.7 V and 5.6 V. Consider the 1.7 MHz switching frequency for capacitor size optimization compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2750 series of low-noise switched-capacitor regulators. It shares the same physical package and core architecture with adjustable variants like the LM2750SD-ADJ/NOPB. The series is designed for space-constrained portable electronics, offering a compact alternative to traditional inductive boost converters while maintaining regulated output stability.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed direct substitutes include the LM2750SD-ADJ/NOPB for adjustable output needs within the same package. Other LM2750 variants with different fixed output voltages may serve as functional replacements if the voltage requirement differs.
