LP2985AIM5-3.0 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 | VIN | power_in | Input supply voltage pin accepting 2.5V to 16V (new chip version) or 3.1V to 16V (legacy version). |
| 2 | GND | power_in | Ground reference connection. |
| 3 | ON/OFF | input | Chip enable input; driving high enables regulator output, driving low disables output and activates internal pulldown to actively discharge VOUT. |
| 4 | BYPASS | bidirectional | Bandgap reference bypass capacitor connection pin; connect external capacitor to ground (typically 10nF) to reduce reference voltage noise for low-noise operation. |
| 5 | VOUT | output | Regulated output voltage pin at 3.0V nominal; connect capacitor ≥2.2µF (legacy chip) or ≥1µF effective (new chip) from pin to ground for stability. |
