TPAX803RS3 from TECH PUBLIC, in a SOT-23. 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 | GND | power_in | Ground. |
| 2 | RESET | output | Open-drain active-low reset output that stays low while VCC is below the reset threshold and for at least 140ms after VCC rises above it. |
| 3 | VCC | power_in | Supply voltage input for +5V, +3.3V, +3V or +2.5V supplies, with a 1.0V to 5.5V operating range (absolute maximum -0.3V to +6.0V). |
