In my circuit, there will be several ICs (one of them is LM555). These ICs are not required most of the time. Therefore I want to keep them shut off and enable them whenever I need, for power consumption issues.
Does a circuit like in the picture do this job? Is there any improvements you could suggest? What kind of a transistor should I use? Should I add a bleeding resistor as well? If Vcc of the main circuit is 5V, what will be the voltage on the Vcc pin of the IC (i.e.; what will be the voltage drop on the transistor?)?
