HE2031A36MPR from HEERMICR, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin. Common return for the regulator and the output load; tie directly to the system ground plane. |
| 2 | VIN | power_in | Unregulated input supply pin. Accepts 1.5V to 25V (absolute max); should be at least Vout + Vdropout ( |
| 3 | VOUT | power_out | Regulated 3.6V output. Delivers up to 400mA with ±1% accuracy (Vout x 0.99 to Vout x 1.01). Recommended output cap Cout = 10uF electrolytic for stability and transient response. |
