HE6236MPR from HEERMICR, in a SOT-89-3. 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 reference; input and output capacitor grounds should return to this pin with wide, short copper traces. |
| 2 | VIN | power_in | Supply input, recommended operating range 2.5V to 18V (absolute maximum -0.3 to 18V), decoupled with a ≥1uF ceramic capacitor to GND. |
| 3 | VOUT | power_out | Regulated 3.6V output for HE6236MPR, delivering at least 500mA, requiring a ≥1uF ceramic output capacitor for stability. |
