TLV803EA43RDBZR

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

TLV803EA43RDBZR 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 RESET output Active-low output reset signal driven low when VDD falls below VIT- (4.38 V); remains low for reset delay period (200 ms) after VDD rises above VIT+ with VOL max 300 mV at 2 mA sink.
2 GND power_in Ground reference for the device.
3 VDD power_in Input supply voltage (1.7 to 6 V) monitored by the device; when VDD falls below VIT- (4.38 V), RESET assertion is triggered.
