the voltage doubling of a the max232 as shown in the datasheets suppose to reach +10V/-10V. However, in practical only +8V/-8V are achieved using the specified cap values. Is there any reason why this happens? thanks

its because according to the MAXIM datasheet, in the MAX232 schematic, the caps are connected to a section called a voltage doubler (+10V) and voltage inverter (-10V) .
Why is 1uF chosen as the cap value? is it due to the fact that it provides a maximum 5V charge ? if so how can i deduce the value? thanks
