Pin Functions

PIN TYPE DESCRIPTION
NAME LM2750-5.0 LM2750-ADJ
CAP+ 10 10 P Flying capacitor positive terminal
CAP– 7 7 P Flying capacitor negative terminal
FB — 3 P Feedback pin
GND 3 — G This pin must be connected externally to the ground pins (pins 5, 6, and the DAP).
GND 5, 6 5, 6 G Ground - These pins must be connected externally.
SD 4 4 I/O Active-low shutdown input. A 200-kΩ resistor is connected internally between this pin and GND to pull the voltage on this pin to 0 V, and shut the part down, when the pin is left floating.
VIN 8, 9 8, 9 P Input voltage - The pins must be connected externally.
VOUT 1, 2 1, 2 P Output voltage - These pins must be connected externally.
DAP √ √ GND The DAP (Exposed Pad) functions as a thermal connection when soldered to a copper plane.
