# TPS3803-01QDCKREP

**Texas Instruments** · Supervisor And Reset ICs · SC-70-5

TPS3803-01QDCKREP from Texas Instruments, in a SC-70-5. 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 | NC | unconnected | No internal connection on the TPS3803-01; leave unconnected. |
| 2 | GND | power_in | Ground reference for all supply and sense voltages; all device voltage limits are specified with respect to GND. |
| 3 | RESET | output | Active-low reset output, open-drain on the TPS3803-01; asserted when VDD or SENSE is below VIT, with a maximum low-output current of 5 mA. |
| 4 | VDD | power_in | Input supply voltage, recommended 1.3 V to 6 V (absolute maximum +7 V), with a 0.1 µF ceramic bypass capacitor advised near the supply terminal for threshold stability. |
| 5 | SENSE | input | Adjustable sense input with negative-going threshold VIT of 1.226 V typical (1.2 V to 1.244 V), input current limited to ±25 nA. |
