DS8242-33S5

DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

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.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper must be back to the DS8242 ground pin using as wide and as short of a copper trace as is practical. 8
