# JY1103-L080AX

**Shenzhen JingYang** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-3L

JY1103-L080AX from Shenzhen JingYang, in a SOT23-3L. 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 | GND | power_in | Power ground (VSS) for the regulator; the datasheet pin table lists GND on SOT23-3L pin 1. |
| 2 | VOUT | power_out | Regulated output (0.8V for the 080 option, up to 300mA maximum output current), with a 1µF output capacitor shown in the typical application. |
| 3 | VIN | power_in | Voltage input, operating range 1.6V to 6.0V (absolute maximum -0.3 to +7.0V), with a 1µF input capacitor shown in the typical application. |
