While this guide has provided an educated framework for understanding the 8681L (assuming it is a low-dropout regulator), Never trust a pinout or maximum rating from a forum or an AI model alone. 8681l ic datasheet

: The AC adapter passes through an input EMI filter and a series protection MOSFET topology before reaching the primary input current sense resistor. [ IN ] --------+--------[ High-Side MOSFET ] --------+----
