Finding a public datasheet can be challenging as some versions are custom-branded for specific manufacturers like Lenovo. However, the general typically covers:
The 8682L employs a rather than a PMOS. This classic bipolar design offers inherent protection against reverse input voltages but comes with a higher quiescent current than modern CMOS LDOs. The internal block diagram reveals: 8682l ic datasheet
