**MICRONE** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

ME6210A50M3G from MICRONE, in a SOT-23. 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 | VSS | power_in | Ground reference pin for the regulator (pin 1 on the SOT23-3 package). |
| 2 | VOUT | power_out | Regulated output pin; the ME6210 output range is 1.5V to 5.0V with up to 500mA output current, and VOUT must stay between Vss-0.3V and Vout+0.3V. |
| 3 | VIN | power_in | Input supply pin; the input voltage range is 2V to 18V with an absolute maximum of 18V. |
