DS8201-33S5 from DSTECH, in a SOT23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input supply pin; the datasheet recommends an input capacitor of 1uF or larger placed close to the VIN and GND pins, and VIN is rated -0.3V to 125V absolute maximum with 3V to 110V recommended operating range. |
| 2 | GND | power_in | Ground pin; input and output capacitor ground connections must be returned to this pin using short, wide copper traces. |
| 3 | EN | input | Enable control input; pulling it low enters shutdown mode with shutdown current of 0.1uA typical and 0.5uA maximum, with EN rising threshold 3.0V and falling threshold 0.6V. |
| 4 | SNS | input | Output voltage sense pin used for output feedback; for DS8201-33 the SNS-to-GND absolute maximum rating is -0.3V to 6V. |
| 5 | VOUT | power_out | Regulated power output pin; the datasheet states a current limit of 140mA typical and a VOUT-to-GND absolute maximum rating of -0.3V to 6V for DS8201-33. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
DS8201-33S5 - Footprint:
Package_TO_SOT_SMD:SOT-23-5 - 3D model: SOT23-5, generated on the KiCad land (body 1.6 x 2.896 mm, terminals on the pads, 1.092 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
