Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-89-3
AP2202R-3.3TRE1 from Diodes Incorporated, 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 | VOUT | power_out | Regulated output voltage; an output capacitor of at least 1.0µF is required to prevent oscillation when CBYP is unused. |
| 2 | GND | power_in | Ground, which is also the TAB (heat-sink tab) on the SOT-89 package. |
| 3 | VIN | power_in | Input voltage; the datasheet recommends VIN of VOUT+0.5V to 13.2V and a 1µF minimum input capacitor between VIN and GND. |
