Analog Switch for Shunting in Resistor on RS485 Lines
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...- HarryRai1984

LDO DC-DC Regulator Help Needed!!!!
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...- HarryRai1984
