LD39020ADM30R from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input supply voltage with operating range 1.5 V to 5.5 V |
| 2 | GND | power_in | Common ground connection to PCB ground |
| 3 | EN | input | Enable control logic input; 0.4 V low threshold activates shutdown mode, 1 V high threshold activates active mode |
| 4 | NC | unconnected | Not internally connected |
| 5 | OUT | output | Regulated output voltage 3.0 V with ±0.5% accuracy tolerance |
