I bought this nice 3V voltage regulator to use in my PIC projects. It has very low supply voltage and good overall characteristics. But, the feature that I probably like the most is the power saving shutdown mode. If the shutdown pin is high then the regulator is enable, and if this pin is low then the regulator is in shutdown mode.
Now come the questions. The datasheet says that this shutdown pin can be controlled from a microcontroller port. Nice, but then how do you make this port high before there is any power in the circuit for the PIC to come up? Remember the shutdown pin has to be high. And when you make this shutdown pin low, it has to stay low otherwise the regulator won't be in power saving mode. Does anybody know of an easy way to make this work?
Thanks,
Robert
