Megain · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4L(1x1)
MG6228D4-33 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 | Regulator output voltage pin; the MG6228 delivers up to 500 mA from this pin, with output selectable from 1.8 V to 5 V at ±2% accuracy. |
| 2 | GND | power_in | Ground pin for the regulator, which must be connected to the system ground. |
| 3 | EN | input | Active-high enable pin: a logic high of at least 0.8 V enables the output, a logic low at or below 0.2 V disables it, and the output capacitor self-discharges when disabled; absolute maximum rating is -0.3 V to +6.5 V. |
| 4 | VIN | power_in | Regulator input voltage pin, with a recommended operating range of 2.5 V to 6 V and an absolute maximum of +6.5 V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
