HT7533S-1 from UMW, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference. Common return for input and output currents; tie directly to the system ground plane. |
| 2 | VIN | power_in | Unregulated input supply. Absolute maximum 30 V; a small (≥1 µF) input capacitor to GND is recommended for stability. |
| 3 | VOUT | power_out | Regulated 3.3 V output (±3%, up to 100 mA). Requires an output capacitor to GND for loop stability and transient response. |
