TPS3809K33DBVT

Texas Instruments · Supervisor And Reset ICs · SOT-23-3L

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.
