HGSEMI · Linear Voltage Regulators (LDO) · TO-220
MIC39300T-5.0 from HGSEMI, in a TO-220. 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 | IN | power_in | Supply input, with a +16V maximum operating supply voltage (absolute maximum ±20V). |
| 2 | GND | power_in | Ground pin, internally connected to the TAB. |
| 3 | OUT | power_out | Regulator output (fixed 5.0V for this MPN) with 3A minimum guaranteed output current. |
