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.
