# TLV803SDBZT

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

TLV803SDBZT 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 for the TLV803 (TLV803SDBZT is the TLV803 base device, S threshold option of 2.93 V). |
| 2 | RESET | output | Open-drain active-low output that is driven to a low impedance state when asserted and remains low for the delay time (td, typically 200 ms) after VDD exceeds VIT-; use a 10-kΩ to 1-MΩ pullup resistor, and the pullup voltage is not limited by VDD. |
| 3 | VDD | power_in | Supply voltage pin, recommended operating range 1.1 V to 6 V; place a 0.1-µF ceramic capacitor close to this pin. |

## CAD (KiCad official)

- Symbol: `TLV803SDBZT`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3 (KiCad packages3D, STEP)
- 3D model files: `tlv803sdbzt-etched.step` / `tlv803sdbzt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tlv803sdbzt.step` / `tlv803sdbzt.glb` are the bare package body.
