# MG6226D4-25

**Megain** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4L(1x1)

MG6226D4-25 from Megain, in a DFN-4L(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 pin, which delivers up to 300 mA of output current. |
| 2 | GND | power_in | Ground connection for the regulator. |
| 3 | EN | input | Enable pin; the datasheet lists an enable-high level of 0.6 V and an enable-low level of 0.2 V. |
| 4 | VIN | power_in | Input voltage pin with a recommended range of 2.5 V to 5.5 V and an absolute maximum of -0.3 V to +6.5 V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
