DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
DS8572-18S5 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, specified for 2.3V to 6V operation, with absolute maximum VIN to GND of -0.3V to 7V. |
| 2 | GND | power_in | Ground reference for the regulator. |
| 3 | EN | input | Enable control input; pulling it low puts the regulator in shutdown, with typical shutdown current of 100nA, and EN to GND absolute maximum is -0.3V to 7V. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, which for this part is 1.8V and supports output load current up to 600mA; VOUT to GND absolute maximum is -0.3V to 6V. |
