We have linear regulator: AMS1117 that I think it must be popular, since many company manufacturing this. Also some have changed it's name slightly to emphasis on their company like LM1117 and LT1117. I think a part has been populated, then many company has manufactured it to with that name and can be placed by previous one without any big stress. Is there some place that has been listed them? or this phenomena happening synonymous, only experience and encountering them in work will lead us to identify them?
Also is there any popular and standard RF component list (mixer, modulator, attenuator, lna ...)?
