AP2127N-1.5TRG1 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 and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin; the datasheet requires a wide copper trace for both VIN and GND, and the input and output capacitors should be placed as close as possible to the device. |
| 2 | VOUT | power_out | Regulated output pin, rated for a minimum maximum output current of 300mA (absolute maximum 450mA), with a 1µF or higher low-ESR X7R/X5R ceramic output capacitor recommended close to VOUT and GND. |
| 3 | VIN | power_in | Power input pin with a recommended input voltage range of 2.5V to 6V and an absolute maximum of 6.5V, decoupled with a 1µF ceramic capacitor placed close to the device. |

- Symbol:
AP2127N-1.5TRG1 - Footprint:
Package_TO_SOT_SMD:SOT-23 - 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.0 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
