LP2986IMX-5.0 from Texas Instruments, in a SOIC-8. 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 | GROUND | power_in | Ground reference for the device. |
| 2 | FEEDBACK | input | Feedback input for output voltage regulation; connect to TAP with OUT tied to SENSE for fixed voltage, or connect to external resistor divider for adjustable output. |
| 3 | TAP | output | Middle tap of internal voltage divider; tie to FEEDBACK with OUT tied to SENSE for fixed voltage output corresponding to part version. |
| 4 | IN | power_in | Input voltage supply with operating range 2.1 V to 16 V. |
| 5 | OUT | power_out | Regulated output voltage with 200-mA maximum output current and typical dropout of 180 mV at 200 mA. |
| 6 | SENSE | input | Sense input for voltage regulation; connect to OUT with FEEDBACK tied to TAP for fixed voltage, or leave open for external resistor divider configuration. |
| 7 | ERROR | output | Open-collector error output that goes low when VOUT drops by 5% of nominal value; requires external pull-up resistor. |
| 8 | SHUTDOWN | input | Active-high enable input; pull low to place regulator in shutdown mode drawing less than 1 μA quiescent current. |
