LP2985AIM5-3.3 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, operating voltage range 2.5V to 16V; use ≥1µF capacitor from this pin to ground. |
| 2 | GND | power_in | Ground reference connection. |
| 3 | ON/OFF | input | Enable pin for the LDO; output is enabled when voltage exceeds high threshold and disabled when below low threshold; tie to VIN if enable function is not used. |
| 4 | BYPASS | bidirectional | Reference bypass pin for low-noise performance; connect external capacitor between this pin and ground to reduce reference voltage noise to 30µVRMS. |
| 5 | VOUT | power_out | Regulated output voltage (3.3V nominal); use ≥2.2µF ceramic capacitor from this pin to ground. |
