DS8242-33S5 from DSTECH, in a SOT-23-5. 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, with a recommended operating range of 2.0V to 24V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | NC | unconnected | No internal connection. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Regulated output of the LDO; for the DS8242-33 variant the output is 3.3V, and the absolute maximum VOUT to GND rating is 6.0V. |
