LP2985IM5-2.7 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; the datasheet recommends a capacitor of 1µF or larger from this pin to ground, and the supply input range is 2.5 V to 16 V for the new chip. |
| 2 | GND | power_in | Ground pin for the regulator, to be connected with the input and output capacitor returns as close together as practical. |
| 3 | ON/OFF | input | Enable input for the LDO: driving it high enables the device and driving it low disables it, with thresholds given in the Electrical Characteristics table; tie to VIN if unused. |
| 4 | BYPASS | bidirectional | Noise-bypass pin where an external capacitor to ground reduces reference voltage noise; the datasheet gives a BYPASS voltage of 1.2 V and an absolute maximum of 3 V for the new chip. |
| 5 | VOUT | power_out | Regulator output; use a capacitor of 2.2µF or larger from this pin to ground, with nominal capacitance above 2.2µF and effective capacitance above 1µF after derating. |
