AX6601-18RA from Axelite Tech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the regulator. Connect to system ground with a low-impedance return path near the input and output decoupling capacitors. |
| 2 | VOUT | power_out | Regulated fixed output voltage (1.8V for the -18 option). Sources up to 300mA. Requires a minimum 2.2µF ceramic capacitor (X5R/X7R) to GND within 1cm for stability. |
| 3 | VIN | power_in | Unregulated input supply, 2.6V to 6V absolute range (must be VOUT + dropout to regulate). Decouple with a 1µF ceramic capacitor to GND placed within 1cm of the pin. |
