A1
VIN
Power Source Input. VIN is the source of the PFET high-side switch. Bypass VIN to GND with a 2.2 μF or greater
capacitor as close to the ADP2108 as possible.
A2
GND
Ground. Connect all the input and output capacitors to GND.
B
SW
Switch Node Output. SW is the drain of the PFET switch and NFET synchronous rectifier.
C1
EN
Enable Input. Drive EN high to turn on the ADP2108. Drive EN low to turn it off and reduce the input current to 0.2 μA.
C2
FB
Feedback Input of the Error Amplifier. Connect FB to the output of the switching regulator.
