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.
V V IN (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.
