Re: Questions about CCD camera design and power supply desig
The requirements for the power supply seem quite stringent to me. Normally a regulator is rated at about 3% regulation over -40C to +85C. Add to that the drift due to the tempco of some divider resistors and you easily get to about 5% drift.
Based on this, I think you should build your P/S using a good quality, low drift reference, low tempco resistors and make it trimmable, for the initial adjustment to bring it well within the 1% range. That way it will be easier to guarantee a maximum 1% drift over temperature.
