TPS3803-01DCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net; no functional purpose on the TPS3803-01. |
| 2 | GND | power_in | Device ground reference. All voltages are measured with respect to this pin. Connect to system ground. |
| 3 | RESET | output | Active-low reset output, open-drain on the TPS3803-01 (requires an external pull-up resistor). Asserted low when SENSE falls below VIT (1.226 V typ) and during power-up while VDD < ~0.8 V. IOL up to 2 mA at VDD = 3.3 V; max sink 5 mA. |
| 4 | VDD | power_in | Input supply voltage. Recommended operating range 1.3 V to 6 V (absolute max 7 V). Typical supply current 2 µA at VDD = 3.3 V. Place a 0.1 µF ceramic bypass capacitor close to this pin for threshold stability. |
| 5 | SENSE | input | Adjustable sense input compared against the internal 1.226 V reference (VIT). Set the monitored trip point with an external resistor divider from the rail being watched to GND. Input current ±25 nA max; input capacitance ~1 pF. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 691 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
