Pinout Table3
| Pin | Signal / Name | Type | Alternative Functions |
|---|---|---|---|
| 1 | GND | Ground | System Ground (0V) — tab is internally connected to GND; use heatsink for loads above ~500mA |
| 2 | VI | Power | Unregulated Negative Input Voltage (-7V to -35V; must be at least 2V more negative than output; add 2.2µF bypass cap to GND near pin) |
| 3 | VO | Power | Regulated Negative Output Voltage (-5V ±4%; max 1A continuous; add 1µF bypass cap to GND near pin) |
