# DS8301A-12S5

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

DS8301A-12S5 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 | Input of supply voltage, recommended operating range 2.0V to 30V with an absolute maximum of -0.3V to 36V relative to GND. |
| 2 | GND | power_in | Ground reference for the regulator; the VIN, EN, VOUT and SNS absolute maximum ratings are all specified to GND. |
| 3 | EN | input | Enable control input that shuts the regulator down when pulled low, with EN rising threshold VIH of 2V and falling threshold VIL of 0.6V, and absolute maximum of -0.3V to 36V to GND. |
| 4 | SNS | input | Sense of output voltage; for adjustable output a resistor divider from VOUT to SNS sets the output, and SNS to GND is rated -0.3V to 6V for the DS8301A-12 (1.2V) variant. |
| 5 | VOUT | power_out | Output of the regulator, supplying up to 400mA load current and stable with a ceramic output capacitor between 1µF and 22µF, with VOUT to GND absolute maximum of -0.3V to 14V. |
