# HX7808CTG

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

HX7808CTG from HANSCHIP semiconductor, in a TO-220-3L. 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 | Power supply input for the regulator; the datasheet limits the input voltage to 35 V maximum and the HX7808C requires at least 11 V at this pin. |
| 2 | GND | power_in | Ground reference pin of the regulator. |
| 3 | OUT | power_out | Regulated output of the HX7808C, 8.0 V typical (7.7 V to 8.3 V at VI=14 V, Io=0.5 A, PD≤15 W), with maximum output current IOM of 1.5 A. |
