LP2985IM5X-4.0 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 accepting 2.5V to 16V (new chip); use ≥1µF capacitor to ground. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | ON/OFF | input | Enable pin for LDO; driving high (>0.85V) enables output, driving low (<0.72V) disables output; tie to VIN if unused. |
| 4 | BYPASS | bidirectional | Reference voltage bypass pin; connect ≥10nF capacitor to ground to reduce reference voltage noise and achieve low-noise performance. |
| 5 | VOUT | power_out | Regulated output pin providing 4.0V nominal output; use ≥2.2µF capacitor to ground. |
