Shenzhen JingYang · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4-EP(1x1)
JY1103-L180QX from Shenzhen JingYang, in a DFN-4-EP(1x1). 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 | VOUT | power_out | Regulated output voltage, selectable 0.8V to 5.0V in 0.05V steps, with up to 300mA maximum output current and a 1uF ceramic output capacitor. |
| 2 | GND | power_in | Power ground (VSS) reference for the regulator. |
| 3 | EN | input | Chip enable input; pulling EN to VSS turns the output off and discharges VOUT through the internal switch. |
| 4 | VIN | power_in | Voltage input, operating range 1.6V to 6.0V, with a 1uF input capacitor. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
