LP2985AIM5-3.8 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 (3.1 V to 16 V for the legacy chip), and a capacitor of 1 µF or larger is required from this pin to ground. |
| 2 | GND | power_in | Ground pin; all device voltages are specified with respect to GND. |
| 3 | ON/OFF | input | Enable pin: driving it high enables the LDO and driving it low disables it, with thresholds given in the Electrical Characteristics table, and it must be tied to VIN if unused (enable voltage 0 V to 16 V for the new chip). |
| 4 | BYPASS | bidirectional | Noise bypass pin, where an external capacitor to ground reduces reference voltage noise, and the BYPASS voltage is rated from -0.3 V to 3 V for the new chip. |
| 5 | VOUT | power_out | Regulator output; use a capacitor of 2.2 µF or larger from this pin to ground, with nominal capacitance greater than 2.2 µF and effective capacitance above 1 µF at the pin, and the output is 1.2 V to 5.0 V for the new chip. |
