LM2750SDX-ADJ

Texas Instruments · DC-DC Converters · WSON-10-EP(3x3)

LM2750SDX-ADJ from Texas Instruments, in a WSON-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Output voltage pin that must be connected externally; for the ADJ version the output is set between 3.8 V and 5.2 V.
2 VOUT power_out Output voltage pin that must be connected externally; for the ADJ version the output is set between 3.8 V and 5.2 V.
3 FB input Feedback pin on the LM2750-ADJ that sets the output voltage; on the LM2750-5.0 this pin is GND instead.
4 SD input Active-low shutdown input with an internal 200-kΩ resistor to GND that pulls the pin to 0 V and shuts the part down when left floating.
5 GND power_in Ground pin that must be connected externally to the other ground pins and the DAP.
6 GND power_in Ground pin that must be connected externally to the other ground pins and the DAP.
7 CAP- passive Flying capacitor negative terminal, connected to the external 1 µF flying capacitor.
8 VIN power_in Input voltage pin that must be connected externally; the input range is 2.7 V to 5.6 V.
9 VIN power_in Input voltage pin that must be connected externally; the input range is 2.7 V to 5.6 V.
10 CAP+ passive Flying capacitor positive terminal, connected to the external 1 µF flying capacitor.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
