# HG7150MK-1

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

HG7150MK-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 pin (地); the datasheet gives no separate electrical limit for this pin and it serves as the common return for VIN and VOUT. |
| 2 | VIN | power_in | Input pin; absolute maximum supply voltage is -0.3 V to +36 V, and the electrical characteristics specify VIN up to 36 V. |
| 3 | VOUT | power_out | Regulated output pin; for the 5.0 V HG7150-1 variant, VOUT is 4.900 V to 5.100 V at IOUT=10 mA and output current is at least 100 mA at VIN=VOUT+2V, and an output capacitor greater than 2.2 uF to ground is required. |
