DS8571-28S5
DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
DS8571-28S5 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, operating range 2.3V to 6V, with absolute maximum VIN to GND of 7V; place at least a 1µF input capacitor close to this pin and GND. |
| 2 | GND | power_in | Ground reference for the regulator; the input and output capacitor grounds must return to this pin through a short, wide trace. |
| 3 | EN | input | Enable control input that shuts the regulator down when pulled low (VIL 0.4V falling, VIH 1.0V rising, 6V absolute maximum to GND), with shutdown ground current of 0.1µA typical. |
| 4 | NC | unconnected | No internal connection on this package variant. |
| 5 | VOUT | power_out | Output of the regulator, 300mA maximum output current, stable with a 1µF to 22µF ceramic or tantalum output capacitor with at least 1mΩ ESR, placed close to VOUT and GND. |
