**HANSCHIP semiconductor** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

HX7815CTG from HANSCHIP semiconductor, in a TO-220-3. 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 | Vcc | power_in | Unregulated supply input; for the HX7815C the input voltage VI is specified at 17.7 V minimum to 35 V maximum, with an absolute maximum input voltage of 35 V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | OUT | power_out | Regulated output; for the HX7815C the output voltage Vo is 14.4 V to 15.6 V (15.0 V typical) at Io = 0.5 A, with a maximum output current IOM of 1.5 A. |
