STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
LD2980ABM30TR 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 | VIN | power_in | Positive supply input; operating voltage range 2.5 to 16 V provides power for the regulator. |
| 2 | GND | power_in | Ground reference pin; return path for all currents. |
| 3 | INHIBIT | input | Logic-controlled ON/OFF shutdown input; output disabled when INHIBIT < 0.18 V, enabled when INHIBIT > 1.3 V; not internally pulled and must not be left floating. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | output | Regulated 3.0 V output; nominal 3.0 V at 1 mA load, range 2.978 to 3.023 V for 1 to 50 mA load at 25°C. |
