TLV803EA22DBZR 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 | tri_state | Active-low open-drain reset output (TLV803E); pulled low when VDD falls below VIT- (2.25 V); remains asserted for the 200 ms reset delay (tD) after VDD rises above VIT+; requires external pull-up resistor; VOL ≤ 300 mV at IOUT(Sink) = 2 mA with VDD = 3.3 V; leakage ≤ 350 nA when deasserted. |
| 3 | VDD | power_in | Input supply voltage, monitored by internal comparator; operating range 1.7 V to 6 V; absolute maximum -0.3 V to 6.5 V; place 0.1 µF to 1 µF bypass capacitor as close to pin as possible. |
