Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-23-5
AP2125K-3.0TRG1 from Diodes Incorporated, in a SOT-23-5. 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 | VIN | power_in | Input voltage pin; the recommended input range is VOUT+0.5V to 6V, with an absolute maximum of 6.5V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | CE | input | Active-high enable input: logic high enables the regulator and logic low shuts it down, with a high threshold of at least 1.5V and a low threshold of at most 0.4V. |
| 4 | NC | unconnected | No internal connection; leave unconnected. |
| 5 | VOUT | power_out | Regulated output voltage pin, 3.0V fixed for this variant with ±2% accuracy. |
