Hi,
I am trying to implement a circuit in which a 120R line termination resistor needs to be connected between the RS 485 A/B lines of a transceiver, driven by a Microcontroller Pin. So the logic is that if Micro Pin = +5V, then analog switch closes, and 120R termination resistor is connected...
Hi,
This post is just to see if someone can clarify a confusion I am having at the moment...
I want to design a DC-DC converter which takes a 12V, 20mA DC input and converts it into a 5V, 0.5A DC output.
I have looked at LDO voltage regulators like the LM2940CT-5.0 and LM7805. My confusion is...
