LD2980CM33TR from STMicroelectronics, in a SOT-23-5L. 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 | VIN | power_in | Input power supply port; operating voltage 2.5 to 16 V DC. |
| 2 | GND | power_in | Ground return pin. |
| 3 | INHIBIT | input | Logic-controlled shutdown input; disables device when VINH < 0.18 V, enables when VINH > 1.3 V, not internally pulled-up. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output voltage port; 3.3 V nominal output at 1 to 50 mA load. |
