TLV803EA29DBZR

Texas Instruments · Monitors & Reset Circuits · SOT-23-3

TLV803EA29DBZR 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.
2 RESET output Open-drain active-low reset output (requires external pull-up resistor, up to 6 V) that is driven low when VDD falls below VIT- and stays low for the 200 ms delay time (tD) after VDD rises above VIT+.
3 VDD power_in Input supply voltage monitored by the device, with a recommended operating range of 1.7 V to 6 V and a 0.1-µF to 1-µF bypass capacitor recommended.
