PIN FUNCTIONS  
VOUT (Pin 1): Low Noise Regulated Output Voltage. VOUT  
should be bypassed with a 2µF low ESR capacitor as  
closetothepinaspossibleforbestperformance.TheVOUT  
range is 2.5V to 5.5V.  
FILT (Pin 3) (LTC1682-3.3/LTC1682-5): This pin is used  
to filter the internal voltage reference. Typically a 1nF  
capacitor is connected from FILT to ground.  
GND (Pin 4): System Ground.  
SHDN (Pin 2): Shutdown Input. A logic low on the SHDN  
pin puts the part in shutdown mode. A logic high enables  
the part. To continuously enable the part connect SHDN to  
VIN. When the part is in shutdown, VOUT will be connected  
to ground via a 100switch and CPO will be high  
impedance disconnected from VIN.  
C(Pin 5): Flying Capacitor Negative Input.  
VIN (Pin 6): Input Voltage, 1.8V to 4.4V. VIN should be  
bypassed with a 2µF low ESR capacitor as close to the  
pin as possible for best performance. A minimum capaci-  
tance value of 0.1µF is required.  
C+ (Pin 7): Flying Capacitor Positive Input.  
FB (Pin 3) (LTC1682):The voltage on this pin is compared  
to the internal reference voltage (1.235V) by the error  
amplifier to keep the output in regulation. An external  
resistor divider is required between VOUT and FB to adjust  
the output voltage.  
CPO (Pin 8): Unregulated Charge Pump Output Voltage.  
Approximately1.95(VIN)atlowloads.Bypasswitha2µF  
low ESR capacitor. If a minimum VOUT enable time is  
required, the CPO capacitor should be 2× the VOUT  
capacitor.
