GR7333-A from GR, in a SOT-89-3. 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 (芯片接地端) for the SOT89-3 variant. |
| 2 | VIN | power_in | Start-up/input terminal (启动输入端) that accepts the unregulated supply; the datasheet limits the input voltage to 15 V maximum, with an absolute maximum input voltage of 18 V. |
| 3 | VOUT | power_out | Chip output terminal (芯片输出端) delivering the regulated output; for GR7333 the output is 3.3 V nominal (3.201 V to 3.399 V at VIN=4.3 V, IOUT=40 mA) with at least 250 mA output current. |
