V
IN
(Pin 1):
Charge Pump Input Voltage. May be between
2.3V and 5.5V. V
IN
should be bypassed with a
4.7
μ
F low
ESR capacitor as close as possible to the pin for best
performance.
V
OUT
(Pin 2):
Regulated Output Voltage for the IC. V
OUT
should be bypassed with a
4.7
μ
F low ESR capacitor as
close as possible to the pin for best performance.
C
+
(Pin 3):
Charge Pump Flying Capacitor Positive Termi-
nal. This node is switched between V
IN
and GND (It is
connected to V
CC
during shutdown).
C
(Pin 4):
Charge Pump Flying Capacitor Negative Termi-
nal. This node is switched between GND and V
OUT
(It is
connected to GND during shutdown).
GND (Pin 5):
Signal and Power Ground for the 6-Pin
SOT-23 package. This pin should be tied to a ground plane
for best performance.
SHDN (Pin 6):
Shutdown. Grounding this pin shuts down
the IC. Tie to V
IN
to enable. This pin should not be pulled
above the V
IN
voltage or below GND.
