Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable pin: pull high to enable the output and low to disable it; it has no internal bias and must be tied to the input voltage or actively driven. |
| 2 | IN | power_in | Input supply pin for the regulator. |
| 3 | GND | power_in | Ground pin of the regulator. |
| 4 | OUT | power_out | Regulated output voltage pin. |
| 5 | ADJ | input | Feedback input to the internal error amplifier that sets the output voltage. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
