-1. Design specifications and requirements:

1.1 Experiment indicators:

(1) require the output voltage Vo =+3 V-+9 V, usually from about 1V-23V

(2) The regulator factor Sv ≦ 3 × 10-3

(3) The ripple voltage Vo p-p ≦ 5mV.

1.2 Experiment Note:

(1) direct access 220V power transformer should be mindful of security

(2) In the bread-board circuit connection has been designed to confirm the positive and negative diodes and capacitors connected correctly.

(3) select the appropriate test equipment, to avoid unnecessary damage or waste of
