JY1117E15AX from Shenzhen JingYang, in a SOT223-3L. 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 | ADJ (GND) | passive | A resistor divider from this pin to the VOUT pin and ground sets the output voltage on the adjustable version, and the pin is ground only for fixed-mode versions. |
| 2 | VOUT | power_out | The output of the regulator, which must be bypassed with a minimum 0.2uF X7R or X5R ceramic capacitor, or a 3.3uF to 100uF electrolytic capacitor with 10mΩ ≤ ESR ≤ 1Ω, to ground to ensure stability. |
| 3 | VIN | power_in | The input pin of the regulator, which must always be at least 1.5V higher than VOUT for proper regulation and is typically decoupled with a large storage capacitor to ground. |
