# JY1106-180EX

**Shenzhen JingYang** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

JY1106-180EX from Shenzhen JingYang, in a SOT-223-4. 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 | GND | power_in | Ground. |
| 2 | VOUT | power_out | LDO output; fixed 1.8V for the -180 option. |
| 3 | VIN | power_in | Voltage input; an input capacitor in the range of 1uF to 10uF is sufficient. |
| 4 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
