Voltage doubler circuit using 555 timer

This voltage doubler circuit use a 555 timer integrated circuit wired as an astable mutivibrator .This voltage doubler circuit can deliver only up to 50mA output current and above that current limit the output voltage will be reduced. The actual output voltage will be around 22V for a 12V DC input and also the output voltage will be a bit unstable. Anyway, for low current applications this circuit is well enough.

Hi, It is written in the description that "This voltage doubler circuit can deliver only up to 50mA output current...". Regarding the datasheets of 1N4148 and 555 (e.g. NE555 (TI))the maximum continous forward current is 200mA and the NE555 can sink up to 200mA, too. Where is that "50 mA" statement came from?
