LM2750LD-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2750LD-5.0/NOPB is a fixed-output boost converter manufactured by Texas Instruments, designed for surface-mount installation in a 10-pin LLP package measuring 3 x 3 x 0.8mm. It operates with an input voltage range of 2.7 V to 5.6 V and provides a fixed output voltage between 4.8 V and 5.2 V. The device delivers a maximum output current of 120 mA with a switching frequency of 1700 kHz and achieves up to 87% efficiency. It functions within a temperature range of -40 °C to +85 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's official datasheet to confirm RoHS compliance and lead-free status. Ensure the package type matches the required PCB layout, as LLP packages have distinct thermal and soldering requirements compared to standard WSON variants. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed output voltage is sufficient, removing the need for external resistors. Consider the 120 mA current limit and 1700 kHz switching frequency for noise-sensitive applications. Evaluate the 3x3 mm package size against available board space and verify that the input voltage range aligns with the source power supply characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2750 series of low-noise switched-capacitor charge pumps from Texas Instruments. These devices are engineered to provide regulated output voltages from single-cell batteries. The series includes adjustable and fixed output variants, offering designers flexibility in creating compact power solutions for portable electronics without the inductor losses typical of traditional boost converters.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2750SD-ADJ/NOPB offers adjustable output voltage in a WSON-10 package. LM2750SDX-5.0/NOPB provides a fixed 5V output in a WSON-EP package. Verify pinout compatibility and thermal performance before substitution.
