DS8241-50S5 from DSTECH, in a SOT23-5. 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 | VIN | power_in | Input of supply voltage; the recommended operating input range is 2.0V to 24V and the absolute maximum VIN to GND is 30V. |
| 2 | GND | power_in | Ground reference pin for the regulator; input and output capacitor grounds should return to this pin through short, wide traces. |
| 3 | EN | input | Enable control input; pulling EN low puts the regulator into shutdown (typical shutdown ground current 0.1µA), with EN thresholds of 1.1V rising and 0.4V falling. |
| 4 | NC | unconnected | No internal connection on the DS8241 (non-N) variant; the SNS sense function on pin 4 applies only to the DS8241N. |
| 5 | VOUT | power_out | Output of the regulator; for the 5.0V option (-50) it is a fixed 5.0V output, with output current limit of 700mA typical and absolute maximum VOUT to GND of 6V. |

DS8241-50S5 - Footprint:
Package_TO_SOT_SMD:SOT-23-5 - 3D model: SOT23-5, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.092 mm tall, datasheet A, midpoint of min and max). Neither the vendor nor KiCad ships a 3D model for this package, so 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)
