TLV803EC29DBZR from Texas Instruments, in a SOT-23. 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 | GND | power_in | Ground reference pin for the device. |
| 2 | RESET | output | Active-low, open-drain reset output (TLV803E): pulled low when VDD falls below the negative threshold voltage VIT-, and remains low (asserted) for the fixed delay time tD after VDD rises back above VIT+; because the output stage is open-drain, an external pull-up resistor to the desired logic rail is required to hold RESET high when deasserted. |
| 3 | VDD | power_in | Input supply voltage pin monitored by the internal comparator; recommended operating range is 1.7 V to 6 V (absolute maximum -0.3 V to 6.5 V), and it also powers the internal bandgap reference, regulator, state machine and logic. |
