Red arrow pointing to component I'd like identified

enter image description here

I have narrowed it down to APR3001/2/3 with datasheet avaialble here: https://www.alldatasheet.com/datasheet-pdf/pdf/149511/ANPEC/APR3001.html

However, the pinout and datasheet do not make sense to me. In the Markings section of the datasheet, they mention that Package code "B" is for the SOT-23-5 pinout while the component in the picture is clearly SOT-23, but has the Package code "B".

Is my component indeed APR3001 or am I missing something?

Just to put it into a perspective this is a Steelseries Arctis 9 wireless dongle receiver/transmitter PCB

Part number is LP2301BLT1G (20V P-Channel Enhancement-Mode MOSFET) see link for datasheet:

01B SOT23 https://www.taobao.com/list/item/655095294882.htm

    \$\begingroup\$ @Nanyo It's a possibility by marking, but the PCB looks like a MOSFET: pin 1 has an RC to it (pull-up for default off, plus slow rise/fall?), pin 2 seems to be a supply (the 5-pin SOT may be a regulator), and pin 3 seems output (drain). There are too many parts and too few codes to identify SMTs uniquely; this is why context matters. \$\endgroup\$ Oct 30, 2023 at 22:00
