LP2980IM5-3.3 from Texas Instruments, 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 | IN | power_in | Input supply pin rated 2.5 V to 16 V (new chip) or 2.2 V to 16 V (legacy chip); requires minimum 1 µF capacitor to ground. |
| 2 | GND | power_in | Common ground and device substrate reference connection. |
| 3 | ON/OFF | input | Active-high logic enable input; output enabled when voltage exceeds 1.6 V (typical) and disabled when below 0.15 V (typical); tie to VIN if shutdown control not required. |
| 4 | N/C | unconnected | Reserved for factory post-packaging test and calibration; leave floating, do not connect to any potential or ground. |
| 5 | OUT | power_out | Regulated 3.3 V output with maximum 50 mA continuous current; requires minimum 2.2 µF output capacitor to ground. |
