HG809LM3-4.63 from HGSEMI, 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 | Chip ground reference. Connect to system ground (0V). |
| 2 | RESET | output | Active-low reset output (RESET with overbar). Asserted low (VOL ≤ 0.3V at ISINK=1.2mA) when VCC falls below Vth (4.63V nominal); driven high (VOH ≥ 0.8*VCC at ISOURCE=500uA) after VCC rises above Vth and the ~200ms power-on reset delay (Trp, 80-350ms) elapses. Rated -0.3V to VCC+0.3V. |
| 3 | VCC | power_in | Supply input and monitored voltage. Operating range 1.0V to 6.0V; absolute max 6.5V. Typical quiescent current 5.5uA at VCC=6V, no load. |
