100mA. I undersntan how we get 100mA (although in theory it should be 158mA, isn’t it? but in reality it might be 100mA). But what is the limiting factor for the voltage?

MOV is for spike protection. You may use 275V MOV.
You can use for 8051 microcontroller with proper filters.

Can i use this with my 8051 microcontroler with rtc.

are you make and test this circuit?

I don’t think it will be easy to achieve. You need very big capacitors for that. Better go for a SMPS power supply.
