# TLV809EA26DBZR

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

TLV809EA26DBZR from Texas Instruments, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the supervisor. DBZ default pinout (no 'R' or 'V' pinout indicator in the ordering suffix) places GND on pin 1. |
| 2 | RESET | output | Active-low push-pull reset output (TLV809E). Driven low when VDD falls below the negative threshold VIT- (2.64 V nominal for the A26 option) and remains asserted for the fixed reset delay time tD (200 ms typ for the 'A' option) after VDD returns above VIT+. VOL ≤ 300 mV at IOL = 2 mA (VDD = 3.3 V); VOH ≥ 0.8·VDD at 2 mA source. Absolute max: -0.3 V to VDD + 0.3 V. |
| 3 | VDD | power_in | Input supply and monitored voltage. Recommended operating range 1.7 V to 6 V; absolute max 6.5 V. Quiescent supply current IDD = 250 nA typ at 3.3 V (1 µA max). This is the rail whose brown-out is being monitored against the internal 2.64 V threshold. |
