# HT7130MK-1

**HGSEMI** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

HT7130MK-1 from HGSEMI, in a SOT-89-3. 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 | GND | power_in | Ground reference pin of the regulator (datasheet pin description: 地, ground). |
| 2 | VIN | power_in | Input pin; the input voltage must not exceed the 30 V maximum rating (absolute maximum range -0.3 to +30 V). |
| 3 | VOUT | power_out | Regulated output pin; the datasheet requires an output capacitor larger than 2.2 uF to ground and recommends a 10 uF polarized capacitor placed close to the VOUT pin. |
