GR7333 from GR, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Chip ground terminal; the datasheet gives no further electrical limit for this pin. |
| 2 | VOUT | power_out | Chip regulated output terminal; for the GR7333 the output is 3.3 V typ (±3%) with at least 250 mA output current at VIN = 4.3 V and VOUT ≥ 2.97 V. |
| 3 | VIN | power_in | Input (start-up input) terminal; VIN input voltage is rated up to 15 V, with an absolute maximum input voltage of 18 V. |
