AMS1085CM-3.3
Public Made by Adomby adom
Advanced Monolithic Systems Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, TO-263-3. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.
← Commit history
page.json: fold the "TAB" entry into pin 2. On TO-263-2 the tab is not a separate pad - it is that lead - so nothing was ever unconnected, but the page listed it as its own pin and pads.json reported pin-not-in-symbol for a pin that cannot exist. Target chosen because net VOUT matches pin 2; the tab's description is merged into that pin rather than dropped.
