AP2115R5-3.3TRG1 from Diodes Incorporated, in a SOT-89-5. 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 | NC | unconnected | No connection; the datasheet's SOT-89-5 table lists this pin as NC/EN, and its SOIC-8 mapping (pins 2, 3, 4 = NC) indicates it is the no-connect pin, with EN on pin 3. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Chip enable: H for normal operation and L for shutdown of the output; the EN pull-down resistor RPD is 3.0 MΩ. |
| 4 | VIN | power_in | Input voltage; the recommended supply range is 2.5 V to 6.0 V and the absolute maximum is 6.5 V. |
| 5 | VOUT | power_out | Regulated 3.3 V fixed output that supplies up to a guaranteed 1 A minimum continuous load current, with 50 mA fold-back short-circuit current limit. |
