LM2750LD-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2750LD-5.0/NOPB is a fixed-output boost converter from Texas Instruments, designed for low-noise applications. It operates with an input voltage range of 2.7 V to 5.6 V and provides a fixed output of 5 V, with a maximum output current of 120 mA. The device utilizes a switched-capacitor topology and features a switching frequency of 1700 kHz. It achieves an efficiency of 87% and is housed in a 10-pin LLP package measuring 3 x 3 x 0.8 mm. The component supports surface mount installation and functions within a temperature range of -40 °C to +85 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Fixed 5 V output capability for stable power delivery
• Low-noise switched-capacitor architecture suitable for sensitive circuits
• Compact 10-pin LLP package for space-constrained designs

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring low noise
• Battery-powered systems with variable input voltages
• Embedded sensor interfaces needing stable 5 V supply

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LD against SDX variants to ensure package compatibility, as LLP and WSON footprints differ. Confirm RoHS compliance status via the manufacturer datasheet before integration. Ensure design reviews account for the fixed 5 V output constraint, as adjustable versions are not available in this part number. Cross-reference pinout diagrams for the 10-pin LLP configuration to prevent assembly errors during PCB fabrication.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required without external resistor programming. The 120 mA current limit suits light-load applications rather than high-power demands. Consider the 1700 kHz frequency for smaller passive components compared to lower-frequency regulators. Evaluate thermal performance within the 3x3mm footprint if ambient temperatures approach the upper operational limit of 85 °C.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2750 series of charge pump converters by Texas Instruments. It is distinct from buck regulators like the LM2594 or other boost variants such as the LM2738. The NOPB suffix indicates lead-free and RoHS-compliant manufacturing. It serves as a specialized solution for step-up conversion where low electromagnetic interference is critical.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2750SDX-5.0/NOPB is a functional equivalent but uses a WSON-10 package instead of LLP. Verify mechanical footprint compatibility before substitution. Other LM2750 variants may offer different output voltages or packaging options.
