# ME6118A50B3G

**MICRONE** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

ME6118A50B3G from MICRONE, in a SOT-223. 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 reference pin for the regulator, shared by the input and output circuits. |
| 2 | VOUT | power_out | Regulated output of the LDO; the datasheet limits VOUT to Vss-0.3 V to VIN+0.3 V and output current to 1.1 A absolute maximum. |
| 3 | VIN | power_in | Power input of the LDO; the datasheet gives an operating range of 2.5 V to 18 V and an absolute maximum input voltage of 18 V. |
