Component Function Description
U1
1
Linear regulator ADP322/ADP323 low dropout linear regulator.
C1, C2, C3, C4, C5, C6 Input capacitor 1 μF input bypass capacitor, 0402 or 0603 case.
JP1, JP2, JP3 3-pin jumper These jumpers connect EN1, EN2, and EN3 to VBIAS for automatic startup.
R1, R2, R3, R4, R5, R6 Resistor
Resistors for setting output voltage for the ADP323, 0603 size. Short R1, R3, and R5 to connect
the output voltage to the feedback input for the ADP322.
