Hi Andrew:

If you are already using 5v in your design and the tolerance of the 3.3v is
about 10% use 2 silicon diodes in series (anode to 5v) this will give 3.6v
if you can live with 10% this is a cheap and reliable solution also you
still have your 5v.

Best Regards

Brian Devlin

Subject: 3.3v Voltage Regulator[OT]


I`m pretty new to this electronic design business and I was wondering if
somebody can help me. I am after a IC capable of turning my 5v regulated
logic supply into exactly 3.3v at max 15mA. Basically a 7805 for 3.3v.
Preferbly in 3 pin package with minimum external components.

Thanks for any help.
