AMS1117M-3.3RG from HANSCHIP semiconductor AMS1117M 3 3RG, in a SOP-8. 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 | ADJ/GND | power_in | Ground / adjust pin. On the fixed-voltage AMS1117-3.3 this pin is the device ground reference (0 V return). On adjustable versions it is the ADJ feedback tap to an external divider. |
| 2 | VOUT | power_out | Regulated 3.3 V output (typ. 3.300 V, min 3.235 V, max 3.365 V over 0≤IOUT≤800 mA, 4.75 V≤VIN≤10 V). Requires ≥22 µF tantalum output capacitor on adjustable version; smaller cap acceptable for fixed version. |
| 3 | VOUT | power_out | Regulated 3.3 V output (paralleled with pin 2, 6, 7). Multiple VOUT pins on SOP-8L reduce lead resistance and improve heat dissipation at 800 mA. |
| 4 | VIN | power_in | Unregulated input supply voltage. Absolute max 15 V; recommended operating VIN ≤ 12 V. Requires ≥10 µF bulk input capacitor. Dropout is typ. 1.2 V at 800 mA (VIN must be ≥ VOUT + Vdrop). |
| 5 | N/C | unconnected | No internal connection. Leave floating or tie to GND per PCB layout preference. |
| 6 | VOUT | power_out | Regulated 3.3 V output (paralleled with pins 2, 3, 7). |
| 7 | VOUT | power_out | Regulated 3.3 V output (paralleled with pins 2, 3, 6). |
| 8 | N/C | unconnected | No internal connection. Leave floating or tie to GND per PCB layout preference. |
