I am currently trying to use a RAK 19007 with a Pololu 12V Step-Up Voltage Regulator U3V70F12.
I am trying to activate a mercury relay, but it seems that the 19007 cannot provide enough current to achieve this. I was unable to find anything about the current output on the datasheet. Is this information available somewhere?
I need 422mA to activate the coil on the mercury relay, but when I have the regulator powered by the J12 header and the mercury switch attached, it drops my input voltage from 3.3 to 3.1, and my output on the regulator goes from 12+V to 4.2V when connected to the relay. The mA are around 160mA.
When I directly connect the regulator to my power source it works correctly.
