DS8401-50S5
DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
DS8401-50S5 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, specified from 2.5V to 36V (absolute maximum 40V), with a 1µF or larger input capacitor placed close to the VIN and GND pins. |
| 2 | GND | power_in | Ground; the input and output capacitor ground connections should use as wide and as short a copper trace as is practical back to this pin. |
| 3 | EN | input | Enable control input; pulling it low shuts the regulator down (shutdown current 100nA typical), with the enable threshold at 1.1V rising and 0.4V falling. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, 5.0V for the DS8401-50S5 variant, rated for 200mA peak output current and stable with a ceramic or tantalum output capacitor of 1µF to 22µF with at least 1mΩ ESR. |
