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

HE6206-25NR from HEERMICR, 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 | GND | power_in | Ground (Vss) pin, the common reference for input, output and the internal voltage reference. |
| 2 | VOUT | power_out | Regulated 2.5V output (±2% accuracy), up to 300mA output current with foldback current limit, used with a 1.0uF ceramic load capacitor. |
| 3 | VIN | power_in | Supply input, rated up to 8V maximum, decoupled with a 1.0uF ceramic input capacitor. |
