Pin Functions
| PIN | I/O | DESCRIPTION | |||
|---|---|---|---|---|---|

| NAME | WSON | WSON | SOT-223 | ||
| DAP | √ | √ | — | — | WSON Only - The DAP (exposed pad) functions as a thermal connection when soldered to a copper plane. See WSON Mounting section for more information. |
| EN | — | 3 | 1 | I | The EN pin allows the part to be turned to an ON or OFF state by pulling this pin high or low. |
| GND | 2 | 2 | 5 | — | Circuit ground for the regulator. For the SOT-223 package this is thermally connected to the die and functions as a heat sink when the soldered down to a large copper plane. |
| IN | 1, 6 | 1, 6 | 4 | I | This is the input supply voltage to the regulator. For WSON devices, both IN pins must be tied together for full current operation (250 mA maximum per pin). |
| N/C | 3 | — | — | — | No internal connection. |
| ADJ | 4 | 4 | 2 | O | The ADJ pin is used to set the regulated output voltage by connecting it to the external resistors R1 and R2 (see 典型应用电路). |
| OUT | 5 | 5 | 3 | I | Regulated output voltage. |
