JY1103-H250BX from Shenzhen JingYang, in a SOT23-5L. 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 | VIN | power_in | Voltage input; operating voltage range is 1.6V to 6.0V. |
| 2 | GND | power_in | Power ground (VSS). |
| 3 | EN | input | Chip enable for the On/Off circuit; pulling EN to VSS turns the output off and discharges the output capacitor through the internal switch. |
| 4 | NC | unconnected | Pin 4 is drawn on the SOT23-5L package but has no entry in the pin table, so no function is stated. |
| 5 | VOUT | power_out | Regulated output; 2.50V for this MPN (code 250), maximum output current 300mA with 300mA over-current limit, 1uF ceramic output capacitor. |
