If you’re running from a noisy source (e.g., a switching buck converter), increase C1 to 47 µF and add a Ferrite bead (L1) of 600 Ω at 100 kHz in series with Vin. This suppresses high‑frequency interference that could otherwise modulate the output.
is a laptop motherboard schematic commonly found in Dell Inspiron 15 (3558/3559/5558/5559) models. The "top" view typically refers to the lad402p schematic top
If you need the (for LAD402P as a chip), here’s the typical configuration (assuming a 12-pin SIP or Multiwatt package): If you’re running from a noisy source (e
