| NAME | VSON | WSON | I/O | DESCRIPTION | ||
|---|---|---|---|---|---|---|
| FIXED | ADJ. | FIXED | ADJ. | |||
| FB | — | 5 | — | 4 | I | In the adjustable configuration, this pin sets the output voltage with the help of the external feedback divider. |
| GND | 4, Pad | 4, Pad | 3, Pad | 3, Pad | — | Ground pin. |
| IN | 1 | 1 | 1 | 1 | I | Input supply pin. Use a capacitor with a value of 0.1 µF or larger from this pin to ground. See the Input and Output Capacitor Requirements section for more information. |
| NC | 2, 3, 5, 6, 7 | 2, 3, 6, 7 | 2, 4, 5 | 2, 5 | — | No connect pin. This pin is not connected internally. Connect this pin to ground for best thermal performance, or leave floating. |
| OUT | 8 | 8 | 6 | 6 | O | Output of the regulator. For the new chip, a capacitor with a value of 1 µF or larger is required from this pin to ground.(1) See the Input and Output Capacitor Requirements section for more information. |
(1) The nominal output capacitance must be greater than 0.47 µF.
Throughout this document, the nominal derating on these capacitors is 50%. Make
sure that the effective capacitance at the pin is greater than 0.47 µF. The
legacy chip is stable for any capacitor value ≥ 0.47 μF.
