TPS3809I50MDBVREP from Texas Instruments, in a SOT-23-3. 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 reference for the supervisor; all voltages are specified with respect to GND. |
| 2 | RESET | output | Active-low reset output that is asserted when VDD is above 1.1 V but below VIT, and returns high after a delay td of 200 ms typical once VDD rises above VIT. |
| 3 | VDD | power_in | Supply voltage input that is monitored against the 4.55 V threshold; recommended operating range is 2 V to 6 V, with a 0.1 µF ceramic bypass capacitor placed near it. |
