do u know a good low dropout and low power 5V regulator which is easily available? I am not sure about availability in your area, but LP2950CZ-5.0 is the one we use. It has few micro-amperes quiscent current. can u suggest me low power eating 51 derivatives. in place of 89c2051 or 89c4051? AT89C2051 can be used at 3V thus reducing the power consumption considerably. |
