LP2985AIM5X-3.3 from Texas Instruments, 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 | Input supply pin; apply supply voltage between 2.5V and 16V with minimum 1µF bypass capacitor to ground. |
| 2 | GND | power_in | Ground reference. |
| 3 | ON/OFF | input | Active-high enable input; output enabled above 0.85V threshold and disabled below 0.72V threshold (new chip version). |
| 4 | BYPASS | output | Bandgap reference bypass output; connect 10nF external capacitor to ground to reduce reference voltage noise. |
| 5 | VOUT | power_out | Regulated 3.3V output voltage; delivers up to 150mA with minimum 2.2µF output capacitor to ground. |
