DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN1x1-4L
DS8561-12D4 from DSTECH, in a DFN1x1-4L. 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 | VOUT | power_out | Output of the regulator; the DS8561 is stable with ceramic output capacitance between 1µF and 22µF and minimum 1mΩ ESR, and VOUT to GND is rated -0.3V to 6V. |
| 2 | GND | power_in | Ground pin; place the input and output capacitor ground connections back to this pin using short, wide copper traces. |
| 3 | EN | input | Enable control input with rising threshold VIH 1.0V and falling threshold VIL 0.4V; EN to GND is rated -0.3V to 6V, and the EN pin is only present on parts ordered with the enable option. |
| 4 | VIN | power_in | Input of supply voltage, specified from 1.2V to 5.5V, with VIN to GND rated -0.3V to 7V; place a 1µF or larger input capacitor close to this pin and GND. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
