GND (Pin 1): Ground. This pin should be tied to a ground
plane for best performance.
V IN (Pin 2): Input Supply Voltage. V IN should be bypassed
with a 1 μ F or greater, low ESR ceramic capacitor.
V OUT (Pin 3): Regulated Output Voltage. V OUT should be
bypassed with a 4.7 μ F or greater, low ESR ceramic capaci-
tor as close to the pin as possible for best performance.
C + (Pin 4): Flying Capacitor Positive Terminal.
C – (Pin 5): Flying Capacitor Negative Terminal.
S ? H ? D ? N ? (Pin 6): Active Low Shutdown Input. A low on S ? H ? D ? N ?
disables the LTC3240-3.3/LTC3240-2.5. This pin is a high
impedance CMOS input pin which must be driven with valid
logic levels. This pin must not be allowed to ?oat.
Exposed Pad (Pin 7): Ground. The exposed pad must be
soldered to PCB ground to provide electrical contact and
optimum thermal performance.
