Measure the voltage going in, and the voltage going out, you can't do any static ohmmeter checks on it. I THINK YHIS IS REQULATOR IC IN MOST DIGITAL SATELLITE RECIEVER Click to expand... No, it would be VERY uncommon, most digital satellite receivers (all?) use switchmode PSU's so don't usually need analogue regulators after the power supply.
