DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-5
DS8601-33S5 from DSTECH, in a SOT23-5. 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 | Power input pin; the recommended input voltage range is 2.0V to 55V, with an absolute maximum of -0.3V to 60V to GND, and a 1uF or larger input capacitor should be placed close to VIN and GND. |
| 2 | GND | power_in | Ground pin, which must be connected to the input and output capacitor ground returns using short, wide traces. |
| 3 | EN | input | Enable control pin; pulling EN low puts the regulator into shutdown with typical shutdown current of 10nA, the EN rising threshold is 2V minimum and the falling threshold is 0.6V maximum. |
| 4 | SNS | input | Output voltage sense pin, where VSNS is 3.3V for the DS8601-33 variant; for adjustable outputs the external divider from VOUT to SNS sets the output voltage, and the absolute maximum for DS8601-33 SNS to GND is -0.3V to 6V. |
| 5 | VOUT | power_out | Regulated output pin, with a maximum rating of -0.3V to 14V to GND, and an output capacitor of 1uF to 22uF with ESR above 1mΩ should be placed close to VOUT and GND. |
