PIN FUNCTIONS DNC (Pins 1,7):
Do Not Connect. Keep leakage current
GND (Pin 4):
Primary Device Ground. Pin 3 and the load from this pin to VIN or GND to a minimum. To minimize ground should be star-connected to Pin 4. leakage due to board contamination, encircle the pin with
V
a metal ring connected to V
OUT (Pin 6):
VOUT Pin. An output capacitor of 1μF or OUT. greater is required for stable operation.
NC (Pin 2, 5):
Not internally connected. May be tied to
V
V
IN (Pin 8):
Power Supply. Bypass VIN with a 0.1μF or IN, VOUT, GND or floated. larger capacitor to GND.
GND (Pin 3):
Internal Function. This pin must be tied to GND near Pin 4.
