LT6656 PIN FUNCTIONS (TSOT-23/DFN)(LS8)GND* (Pin 1/Pin 3): Internal Function. This pin must be NC (Pins 1, 2, 7): Not Internally Connected. May be tied tied to ground. to VIN, VOUT, GND or floated. GND (Pin 2/Pin 2): Device Ground. GND* (Pin 3): Internal Function. This pin must be tied NC (Pins 3, 5/Pins 1, 5): Not Internally Connected. May to ground. be tied to VIN, VOUT, GND or floated. GND (Pin 4): Device Ground. VIN (Pin 4/Pin 6): Power Supply. The minimum supply VOUT (Pin 5): Output Voltage. A minimum output capacitor varies with output load and voltage option, see the Dropout of 1µF is required for stable operation. Voltage specification in the Electrical Characteristics table V for further details. The maximum input voltage is 18V. OUT (Pin 6): Output Voltage. Tie to pin 5 for best load regulation. Bypass VIN with a 0.1µF capacitor to ground. VVIN (Pin 8): Power Supply. Bypass VIN with a 0.1µF OUT (Pin 6/Pin 4): Output Voltage. A minimum output capacitor to ground. capacitor of 1µF is required for stable operation. GND*(Exposed Pad Pin 7, DFN Only): This pin must be tied to ground.
