DS8201-A1S5

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

DS8201-A1S5 from DSTECH, in a SOT23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power input pin. Accepts 3V to 125V DC (absolute max) and up to 110V recommended. Bypass to GND with a >=1uF ceramic capacitor placed close to the pin.
2 GND power_in Device ground reference. Connect via short, wide traces to the input and output capacitor return.
3 EN input Enable control input. Drive high (>=3.0V) to enable the regulator; drive low (<=0.6V) to enter shutdown mode where Iq drops to ~100nA. Typical EN input current 10nA at VEN=36V. A 1K series resistor is recommended in the typical application.
4 SNS input Output voltage feedback / sense input. For the fixed 12V (A1) variant, tie SNS directly to VOUT. Can also be driven from a resistor divider from VOUT for adjustable output (up to 24V max). SNS input current ~0.85uA typical.
5 VOUT power_out Regulated power output. Delivers up to 80mA at the programmed VSNS voltage (12V for the -A1 option). Bypass to GND with a >=1uF ceramic capacitor (up to 22uF, ESR >=1 mOhm) placed close to the pin.
