# DS8201-50S5

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

DS8201-50S5 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 supply input. Absolute maximum 125 V to GND; recommended operating range 3.0 V to 110 V. Place a >=1 uF ceramic cap close to this pin and GND. |
| 2 | GND | power_in | Device ground reference. |
| 3 | EN | input | Enable control input. VIH >= 3.0 V (rising) turns the regulator on; VIL <= 0.6 V (falling) puts the chip into shutdown (~100 nA typ). IEN typ 10 nA at VEN=36 V. Do not float; pull high (e.g. via a 1K series resistor) to enable. |
| 4 | SNS | input | Output voltage sense/feedback input. For the fixed-output -50 variant, tie SNS to VOUT for 5.0 V regulation. Can also be driven by an external R1/R2 divider from VOUT for adjustable outputs (1.8 V to 24 V); divider current should be >50 uA. ISNS typ 0.85 uA. |
| 5 | VOUT | power_out | Regulated LDO output. Fixed 5.0 V for the -50 option, up to 80 mA. Current-limited to ~140 mA typ. Place a 1 uF to 22 uF output capacitor (ceramic or tantalum, ESR >= 1 mOhm) close to the pin. |
