- Im making a small device to produce in small amounts and found a deal
- for 12v 200ma dc adapters at only 95 cents a piece from parts express.
- Its rated at 200 ma which is more than my circuit needs. My only problem
- is that its replacing a 17vdc and a 7812 regulater chip which provides
- quite a stable 12 volts. Im also using a 470uF capacitor for filtering.
- Are DC adapters pretty regulated on their own. If I dont exceed the
- amperage can I be sure that the output voltage will notmuch below
- 12 volts even if I continue to use the filter capacitor. I would appreciate
- any help. This would save me over $1 $10 iich could add up.ld add up.
