Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-23
AP7375-33SA-7 from Diodes Incorporated, 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 | VIN | power_in | Input voltage pin, operating range 3.0V to 45V (absolute maximum 55V), with a 1µF ceramic input capacitor recommended close to VIN and GND. |
| 2 | VOUT | power_out | Regulated 3.3V output (±2%) delivering up to 300mA, requiring an output capacitor of at least 1µF (10µF typical) placed close to the pin. |
| 3 | GND | power_in | Ground pin, to be connected to the external circuit ground. |
