LM2750SD-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2750SD-ADJ/NOPB is a low-noise switched-capacitor charge pump voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 2.7 V to 5.6 V and provides an adjustable output voltage between 3.8 V and 5.2 V. The device delivers a maximum output current of 120 mA through a single output channel. Key electrical parameters include a switching frequency of 1.7 MHz and a typical quiescent current of 5 mA. It functions within a temperature range of -40°C to +85°C and utilizes a WSON-10 surface-mount package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's official documentation to confirm lead-free compliance and exact pinout compatibility. Ensure the ordering code matches the required adjustable variant rather than fixed-output versions within the same series. Cross-reference the datasheet revision history for any updates to thermal or electrical specifications prior to finalizing procurement orders.
