Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable (Input): active-high CMOS-compatible control input that must not be left floating. |
| 2 | IN | power_in | Unregulated input, +2.8V to +16V maximum. |
| 3 | GND | power_in | Ground; the TAB is also connected internally to the IC's ground on this package. |
| 4 | OUT | power_out | Regulator output voltage. |
| 5 | ADJ | input | Feedback voltage input: 1.24V feedback from the external resistor divider that sets the output voltage (VOUT = 1.242 × (R1/R2 + 1)). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
