CBM810LST3 from Corebai Microelectronics, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference; all signals are referenced to ground (0 V). |
| 2 | RESET | output | Logic-high push-pull reset output that is driven high while VCC is below the reset threshold and stays high for 240 ms (typical) after VCC rises above the threshold. |
| 3 | VCC | power_in | Monitored supply voltage; the device operates from 1.0 V to 5.5 V. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
CBM810LST3 - Footprint:
Package_TO_SOT_SMD:SOT-23-3 - 3D model: SOT-23-3, generated on the KiCad land (body 1.3 x 2.92 mm, terminals on the pads, 1.0050000000000001 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
