Megain · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
MG6228T5-33 from Megain, in a SOT-23-5. 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 | VIN | power_in | Input voltage pin; the recommended operating input range is 2.5 V to 6 V, and the absolute maximum rating is -0.3 V to +6.5 V. |
| 2 | GND | power_in | Ground pin for the regulator. |
| 3 | EN | input | Active-high enable pin: the input must be at least 0.8 V to enable the output and no more than 0.2 V to disable it, with an absolute maximum of -0.3 V to +6.5 V, and the output capacitor self-discharges when the part is disabled. |
| 4 | NC | unconnected | No internal connection; the pin is left floating (悬空) and is not used. |
| 5 | VOUT | power_out | Regulated output voltage pin, adjustable in the datasheet range of 1.8 V to 5 V with ±2% accuracy and up to 500 mA output current. |
