TLV803EA30DCKR

Texas Instruments · Supervisor And Reset ICs · SC-70-3

TLV803EA30DCKR from Texas Instruments, in a SC-70-3. 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 Device ground return. Connect to the system ground plane; place bypass capacitor on VDD referenced to this pin.
2 RESET output Active-low, open-drain reset output (TLV803E variant). Driven low when VDD falls below the negative threshold VIT- (3.0 V nominal for the '30' option) and remains asserted for the delay time tD (200 ms typ, 'A' option) after VDD rises above VIT+. Requires an external pull-up resistor to VDD or another rail (RESET current ≤ ±5 mA recommended).
3 VDD power_in Input supply voltage and the monitored rail. Recommended operating range 1.7 V-6 V (absolute max 6.5 V). Bypass with a ceramic capacitor to GND close to the pin.
