How can I design a discrete linear stabilised power supply circuit that will have 230V/50Hz input and give output of 10V, 1A dc using discrete components (not OpAmp).the circuit should have a short-circuit protection (current limiting)

• Input Voltage: mains 230V, 50Hz
• Output Voltage: 10V
• Maximum output current: 1A
• Short-circuit protection
• Current limiting
 

To do that without substantial power loses the input ac voltage has to be stepped down form 230Vac to roughly 15Vac ..
Can use a step-down transformer?

Hi,
First you need to step down the voltage from 220vac to around 12vac, higher will do, but more heat will result as more voltage needs to be dissipated by the regulator if linear. So, then you need to convert the AC to DC with a bridge rectifier or a full wave rectifier if a centre tapped transformer is used. Filter the output with bulk caps and decoupling caps. Then rectify it. You CAN use switching regulators, but for your requirements linear regulator is to be used.

Hope this helps.
