APX803L20-18SA-7 from Diodes Incorporated, 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 | GND | power_in | Ground reference for the device. Connect to the system ground plane. |
| 2 | RESET | output | Reset output pin. Open-drain, active-low. Asserts low when VCC drops below the 1.8V threshold and remains low for the 220ms active timeout after VCC recovers. Requires an external pull-up resistor (typ. 100kΩ). VOL ≤ 0.4V at ISINK = 3.5mA; absolute max VRESET = 6.0V; IO max = 20mA. |
| 3 | VCC | power_in | Operating voltage input / monitored supply. Recommended operating range 0.9V to 5.5V (absolute max 6.0V). Typical supply current 1µA. Bypass with a 100nF ceramic capacitor to GND close to the pin. |
