2T03-01QDCKRG4Q1 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 GND for best PCB robustness. |
| 2 | GND | power_in | Device ground reference. All voltage measurements are with respect to this pin. |
| 3 | RESET | output | Active-low reset output. On the TPS3803-01-Q1 this is an open-drain output (requires an external pull-up, typ. 50 kΩ to VDD); VOL ≤ 0.3 V at up to 3 mA. Asserted (low) whenever SENSE is below VIT = 1.226 V (typ) or during power-on until VDD exceeds ~0.8 V. |
| 4 | VDD | power_in | Input supply voltage, 1.3 V to 6 V recommended (7 V absolute max). Supply current ~2 µA typ at 3.3 V. TI recommends a 0.1-µF ceramic bypass capacitor placed close to this pin. On TPS3803-01-Q1 VDD is only the supply; the monitored rail is applied at SENSE via a resistor divider. |
| 5 | SENSE | input | Adjustable sense input. Compared against an internal 1.226 V reference (VIT: min 1.2 V, typ 1.226 V, max 1.244 V). Input current ±25 nA max, input capacitance ~1 pF. External resistor divider R1/R2 sets the monitored threshold: VIT' = (1 + R1/R2) × 1.226 V. A 1 nF-10 nF decoupling capacitor near this pin is recommended. |
