JY1105-L180BX 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 | Input supply pin, operating range 1.7V to 6.0V, with a 1uF or greater capacitor to ground placed close to the device. |
| 2 | VSS | power_in | Ground pin (VSS) of the regulator. |
| 3 | EN | input | Active-high enable input, high level 1.2V to 6V and low level 0.3V max; pulled down internally by 4MΩ, so open or low puts the device in standby with 0.2uA max. |
| 4 | NC/ADJ | unconnected | No connect on the fixed-output JY1105NF such as the L180 version, and feedback Adj input (0.6V reference) only on the adjustable JY1105AF. |
| 5 | VOUT | power_out | Regulated output pin, 500mA maximum output current, with a 1uF or greater output capacitor to ground (3.3uF for Vout below 1.2V). |
