TLV803EA26RDBZR

Texas Instruments · Supervisor and Reset ICs · SOT-23

TLV803EA26RDBZR from Texas Instruments, in a SOT-23. 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 RESET output Active-low, open-drain reset output. Driven low when VDD falls below the negative threshold VIT- (~2.63 V for the -26 option) and remains asserted for the reset time delay tD (~200 ms for the -A option) after VDD rises above VIT+. Requires an external pull-up resistor (typ. 10 kΩ) to VDD or another rail up to 6 V because this is the TLV803E open-drain variant.
2 GND power_in Ground reference for the supervisor. Connect to the system ground plane.
3 VDD power_in Input supply voltage and monitored rail. Recommended operating range 1.7 V to 6 V (absolute max 6.5 V). Typical supply current IDD = 250 nA at VDD = 3.3 V; 0.4 μA typical at 6 V.
