LP2985IM5-3.1 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 pin, with an input range of 2.5 V to 16 V for the new chip, and it needs a capacitor of 1 µF or larger from this pin to ground. |
| 2 | GND | power_in | Ground pin, which is the reference for all voltages on the device. |
| 3 | ON/OFF | input | Enable pin where driving high enables the regulator and driving low disables it, with high and low thresholds given in the Electrical Characteristics table, and it must be tied to VIN if unused. |
| 4 | BYPASS | bidirectional | Noise bypass pin where an external capacitor to ground reduces reference voltage noise, and the BYPASS voltage is limited to 3 V maximum for the new chip. |
| 5 | VOUT | power_out | Regulator output that needs a capacitor of 2.2 µF or larger to ground, with the output voltage range of 1.2 V to 5.0 V for the new chip. |
