Voltage doubler with IC 555

U1 NE555 timer IC
R1 2.2k ohm resistor
R2 15k ohm resistor
C1 0.01 uF ceramic capacitor
C2, C3 220 uF electrolytic capacitor
C4 470 uF electrolytic capacitor
D1, D2 1N4002 diode

all resistors are 5 or 10 percent tolerance, 1/4-watt
all capacitors are 10 percent tolerance

this circuit rougly doubles the voltage of the input, however the current output is low. doubled output is at ‘V source.’ Multiple Supply Circuit
