What this charge pump delivers for your rail
The Texas Instruments LM2750LD-ADJ/NOPB is a switched-capacitor charge-pump step-up regulator that delivers a regulated adjustable output from 3.8 V up to 5.2 V at up to 120 mA. It runs from a 2.7 V to 5.6 V input rail and switches at 1.7 MHz, keeping external capacitors small — two ceramic flying caps and one output cap are typical. The 10-WSON (3x3 mm) exposed-pad package makes it a fit for compact portable or battery-powered boards where a small inductorless boost is needed. No synchronous rectifier on this part; the charge-pump topology handles the step-up internally without magnetics. Temperature grade spans -40°C to 125°C, so it can live in an outdoor telecom module, an industrial sensor head, or an engine-bay-adjacent ECU that doesn't need the full AEC-Q100 qualification. The single positive output is adjustable via an external resistor divider, giving the designer flexibility to set the rail exactly where the load needs it.
Package and mounting — 10-WSON with exposed pad
The 10-WSON (3x3 mm) exposed-pad package is a surface-mount part. The exposed pad on the underside must be soldered to a PCB thermal land for heat sinking.
What the ratings mean for your design
The 120 mA output current is the limit. Input voltage range covers 2.7 V to 5.6 V. Adjustable output from 3.8 V to 5.2 V.
