HT7533MK-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); the datasheet gives no separate electrical limit for this pin, and the absolute maximum supply rating is -0.3 to +30 V. |
| 2 | VIN | power_in | Input pin; the supply voltage must not exceed 30 V (absolute maximum range -0.3 to +30 V), and VIN should be at least VOUT+2 V for the stated electrical characteristics. |
| 3 | VOUT | power_out | Regulated output pin; it supplies up to 100 mA typical (70 mA minimum at VIN=VOUT+2V), and the datasheet requires an output-to-ground capacitor greater than 2.2 uF. |
