Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Regulator input; supply voltage can range from 2.7V to 11.5V. |
| 2 | GND | power_in | Ground pin that also functions as a heatsink on the SOIC package and must be soldered to the circuit board, connected to large copper pads or planes to channel heat from the IC. |
| 3 | GND | power_in | Ground pin that also functions as a heatsink on the SOIC package and must be soldered to the circuit board, connected to large copper pads or planes to channel heat from the IC. |
| 4 | OFF | input | Active-low shutdown input; logic levels must switch in less than 1µs, with the high level above the OFF threshold. |
| 5 | SET | input | Feedback input for setting the output voltage; connect to GND for the preset 3.3V output, or to an external resistor network for adjustable operation. |
| 6 | GND | power_in | Ground pin that also functions as a heatsink on the SOIC package and must be soldered to the circuit board, connected to large copper pads or planes to channel heat from the IC. |
| 7 | GND | power_in | Ground pin that also functions as a heatsink on the SOIC package and must be soldered to the circuit board, connected to large copper pads or planes to channel heat from the IC. |
| 8 | OUT | power_out | Regulator output, fixed at 3.3V or adjustable from 1.25V to 11.0V; sources up to 500mA for input voltages above 4V. |
