MG6228T3B-30

Megain · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

MG6228T3B-30 from Megain, in a SOT-23-3. 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 GND power_in Ground pin of the regulator (接地端); the datasheet gives no electrical limit for this pin.
2 VOUT power_out Regulated output voltage pin; the device is rated for up to 500 mA output current with output options of 1.8 V to 5 V and ±2% tolerance.
3 VIN power_in Input voltage pin; recommended operating range is 2.5 V to 6 V, with an absolute maximum of -0.3 V to +6.5 V.
