TPS3809K33DBVT from Texas Instruments, in a SOT-23-3L. 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 connection; should be connected with low-impedance connection. |
| 2 | RESET | output | Active low reset output; asserts when VDD is below threshold voltage VIT and deasserts after delay td when VDD rises above VIT with push-pull output stage. |
| 3 | VDD | power_in | Supply voltage input for 2V to 6V operating range; 0.1-µF ceramic capacitor to ground recommended to improve threshold voltage stability. |
