DS8561-12S5

DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-5

DS8561-12S5 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, operating range 1.2V to 5.5V (absolute max -0.3V to 7V), with a 1µF or larger capacitor placed close to VIN and GND.
2 GND power_in Ground.
3 EN input Enable control input; pulling it low shuts down the regulator (VIH 1.0V rising, VIL 0.4V falling, absolute max 6V).
4 NC unconnected No internal connection.
5 VOUT power_out Regulator output (fixed 1.2V for this part), needs 1µF to 22µF output capacitor close to VOUT and GND, up to 300mA.

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 DS8561 ground pin using as wide and as short of a copper trace as is practical. 13
