**MICRONE** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

ME6119A44PG from MICRONE, in a SOT-89-3. 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 | VSS | power_in | Ground pin, the common reference for the LDO, per the ME6119AXX pin table. |
| 2 | VIN | power_in | Power input; the datasheet gives an operating input range of 2.5V to 18V and an absolute maximum input voltage of 18V. |
| 3 | VOUT | power_out | Regulated output; absolute maximum VOUT is Vss-0.3V to VIN+0.3V and the maximum output current is 400mA. |
