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