DS9801BS6 from DSTECH, in a SOT-23-6. 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 | GND | power_in | Ground pin, which the datasheet requires to be connected to the ground plane; input and output capacitor grounds must return to the GND pins with short, wide traces. |
| 2 | GND | power_in | Ground pin, which the datasheet requires to be connected to the ground plane; input and output capacitor grounds must return to the GND pins with short, wide traces. |
| 3 | VIN | power_in | Power input port with a recommended input voltage of 2.2V to 6V and an absolute maximum VIN-to-GND rating of -0.3V to 36V. |
| 4 | VOUT | power_out | Power output port, whose absolute maximum VOUT-to-GND rating is -0.3V to 6V. |
| 5 | GND | power_in | Ground pin, which the datasheet requires to be connected to the ground plane; input and output capacitor grounds must return to the GND pins with short, wide traces. |
| 6 | GND | power_in | Ground pin, which the datasheet requires to be connected to the ground plane; input and output capacitor grounds must return to the GND pins with short, wide traces. |
