LP2988AIMX-3.3 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 | passive | A single external capacitor on the Bypass pin reduces regulator output noise (LP2988 only). |
| 2 | DELAY | passive | A capacitor connected to the DELAY pin sets the power-ON reset delay, and the error flag then provides the power-ON reset signal. |
| 3 | GROUND | power_in | Ground reference for the regulator. |
| 4 | INPUT | power_in | Unregulated supply input; operating range is 2.1V to +16V with survival to −0.3V to +16V. |
| 5 | ERROR | output | Error flag goes low when the output drops approximately 5% below nominal. |
| 6 | SHUTDOWN | input | Shutdown control; the regulator draws less than 2 µA quiescent current when this pin is held low, and its survival rating is −0.3V to +16V. |
| 7 | OUTPUT | power_out | Regulated output rated 200 mA continuous with short-circuit protection; survival voltage is −0.3V to +16V. |
| 8 | SENSE | input | Sense input for the output voltage feedback; survival rating is −0.3V to +6V. |
