# HG7530MK-1

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

HG7530MK-1 from HGSEMI, in a SOT-89. 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 pin (地) of the LDO, serving as the common return for the input and output. |
| 2 | VIN | power_in | Input pin; the datasheet rates the supply voltage from -0.3V to +36V and requires VIN of at least VOUT+2V for the stated test conditions. |
| 3 | VOUT | power_out | Regulated output pin; the 7530-1 version gives 3.0V nominal with up to 100mA output current, and an output capacitor greater than 2.2uF to ground is required. |
