RM9XG sot23-5 component

felipeab79 over 1 year ago

Hello, greetings from Auckland NZ.

I am looking for part number of this component installed on pcb board.

I would appreciate if you can guide me to find this component.

Thanks in advance,

Felipe

The RM9sE looks like a adjustable linear regulator with standard pinout:

1: input with an input cap to GND

2: GND

3: enable, active high

4: FB, feedback with a resistor divider from output voltage - FB - GND

5: Output with output cap.

As the trace for the output voltage is not very thick it might be a reference voltage, or an analog voltage feed only a few components. If you find other component pins connected to the same net as pin5, they might have better markings for identification that you get at least an idea of the voltage range of the output voltage.

The 2nd, RM9xG could be the same/similar component, just a different layout for input, output caps and feedback resistors.

And there might be a solder bridge between pin 1 and 2 on the RM9sE, if it is not only a shadow or reflection in the image.
