TLV803EF29DBZR

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

TLV803EF29DBZR 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 reference; connect to system ground plane.
2 RESET output Open-drain active-low reset output; driven low when VDD falls below VIT- (2.93 V for this variant) and remains asserted for the reset delay period tD (400 ms typ) after VDD rises above VIT+; maximum sink current 5 mA, VOL ≤ 300 mV at 2 mA sink with VDD = 3.3 V; open-drain leakage Ilkg(OD) ≤ 350 nA at VDD = VPULLUP = 6 V; requires external pull-up resistor up to 6.5 V.
3 VDD power_in Input supply voltage (1.7 V to 6 V operating, abs max 6.5 V); monitored by the internal comparator against the fixed threshold VIT- = 2.93 V; IDD = 250 nA typ / 1 µA max at 3.3 V; a 0.1 µF to 1 µF bypass capacitor is recommended.
