LP2989IMX-1.8 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 | BYPASS | input | Bypass capacitor input used to connect the external noise-reduction capacitor. |
| 2 | N/C | unconnected | Reserved for post-packaging test and calibration of VOUT accuracy; it must be left floating, not connected to any potential or ground, and pin continuity testing on it is discouraged. |
| 3 | GROUND | power_in | Ground pin for the regulator. |
| 4 | INPUT | power_in | Regulator power input. |
| 5 | OUTPUT | power_out | Regulated output voltage. |
| 6 | SENSE | input | Feedback voltage sense input. |
| 7 | ERROR | output | Error signal output. |
| 8 | SHUTDOWN | input | Shutdown input. |
