JY803-293NRX from Shenzhen JingYang, 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 / negative supply reference pin (VSS). Connect to system ground. |
| 2 | VIN | power_in | Input / monitored supply voltage pin (VCC). Operating range 1.2 V to 7.5 V; absolute max 8.0 V. This is the voltage being supervised against the 2.93 V detect threshold. |
| 3 | RESET | output | N-channel open-drain active-low reset output. Pulls low when VIN falls below the 2.93 V detect threshold and remains low for a 200 ms (typ) reset active timeout after VIN recovers. Requires an external pull-up (typ. 100 kΩ per application circuit). |
