HT7533H23 from HX hengjiaxing, in a SOT-23-3. 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, the common reference for the regulator (listed as 地 in the datasheet pin function table). |
| 2 | VIN | power_in | Input pin; the input voltage must stay within the absolute maximum rating of -0.3 V to +30 V, and input capacitors should be placed close to this pin. |
| 3 | VOUT | power_out | Regulated output pin; an output capacitor greater than 2.2 µF must be connected from this pin to ground, with tantalum capacitors recommended. |
