SOT-23 Component Identification with label EJVK2
The best option I can find would be the Nexperia PMV33UPE, a P-Channel Power MOSFET with marking EJ%.
The % in the marking is a placeholder for a manufacturing code, which I cannot find any further details on. It could conceivably be multiple characters, perhaps including date code information.
The pin-out seems to make sense, in both cases the gate is connected to the skinny trace in your image, and the source/drain are connected to fat traces. In the case of the lower right, the source connectes to C68 and a possible power plane. The drain connects to an inductor, along with the cathode of a diode (whose anode is GND). This would be the classic topology of a Buck converter, so would make sense for a PMOS with this pinout to be used.
