HE6233MPR from HEERMICR, in a SOT-89. 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 leftmost lead in the SOT89 top view. |
| 2 | VIN | power_in | Supply input, rated for input voltage up to 15V (absolute maximum supply voltage 18V), with 1uF input capacitor recommended; the center lead. |
| 3 | VOUT | power_out | Regulated 3.3V output (HE6233, ±2% tolerance) delivering more than 500mA, with 1uF tantalum or 6.8uF ceramic output capacitor recommended. |
