# TLV809L30DBZR

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

TLV809L30DBZR 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 pin; this pin must be connected to ground with a low-impedance connection. |
| 2 | RESET | output | Active-low push-pull RESET output that asserts when VDD is below the threshold voltage VIT and deasserts after the delay time td once VDD rises above VIT. |
| 3 | VDD | power_in | Supply voltage pin with a recommended supply range of 2 V to 6 V; a 0.1-µF ceramic capacitor from this pin to ground is recommended to improve threshold stability. |
