HE6233MPR

HEERMICR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

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.
