GND (Pin 1, 7): Ground. These pins should be tied to a
ground plane for best performance. The exposed pad must
be soldered to PCB ground to provide electrical contact
and optimum thermal performance.
V
IN
(Pin 2): Input Supply Voltage. V
IN
should be bypassed
with a 1µF to 4.7µF low ESR ceramic capacitor.
V
OUT
(Pin 3): Regulated Output Voltage. V
OUT
should be
bypassed with a low ESR ceramic capacitor providing at
least 2µF of capacitance as close to the pin as possible
for best performance.

N disables the LTC3204-3.3/LTC3204-5/LTC3204B-3.3/
LTC3204B-5. This pin must not be allowed to float.
