Pinout Table3
| Pin | Signal / Name | Type | Alternative Functions |
|---|---|---|---|
| 1 | VI | Power | Unregulated Input Voltage (+14.5V to +35V; minimum ~2V above output for regulation; add 0.33µF bypass cap to GND near pin) |
| 2 | GND | Ground | System Ground (0V) — tab is internally connected to GND; use heatsink for loads above ~500mA |
| 3 | VO | Power | Regulated Output Voltage (+12V ±4%; max 1A continuous; add 0.1µF bypass cap to GND near pin) |
