APX809-23SRG-7 from Diodes Incorporated, in a SOT-23R. 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 | Push-pull reset output, active low for the APX809, asserted when VCC falls below the 2.25V typ threshold (APX809-23) and held for 200ms typ (140 to 280ms) after VCC rises above it. |
| 2 | GND | power_in | Ground. |
| 3 | VCC | power_in | Operating voltage input, 1.1V to 5.5V recommended (absolute maximum -0.3 to +6.0V). |
