Quick summary
The part number string "8681L" is ambiguous. Two main families appear in datasheet searches:
Review of the "8681L" Search Result Quality
- No datasheet from TI, ADI, Maxim, Microchip, ON Semi, or ST.
- No listing on AllDatasheet, Alldatasheet.com (often spammy), or Octopart.
- Generic search results return unrelated products (LED drivers, RF modules, or counterfeit listings on Alibaba).
At 25°C ambient, TJ = 152.5°C → Exceeds maximum rating (125°C). Solution: Use a lower input voltage, reduce current, or switch to a larger package like SOT-89. 8681l ic datasheet

Applications
References & Further Reading
Application Notes and Typical Circuits Datasheets often contain typical application circuits showing recommended external components and layout tips. For a switching regulator type 8681L, the schematic will specify inductor value, input and output capacitors, and diode or synchronous MOSFET arrangements. For LDOs, recommended output capacitor values and ESR ranges are critical; using an out-of-spec capacitor can cause instability. Designers should follow the recommended BOM and PCB layout examples closely to achieve the performance shown in the datasheet graphs (e.g., transient response, output ripple). Quick summary The part number string "8681L" is ambiguous
The datasheet’s PSRR (Power Supply Rejection Ratio) is poor by design (GaAs FETs are not op-amps). If you have a 100 mVpp ripple on your 3.3V rail, you will see that ripple as phase noise on your output. No datasheet from TI, ADI, Maxim, Microchip, ON Semi, or ST
