Pinout Table3
| Pin | Signal / Name | Type | Alternative Functions |
|---|---|---|---|
| 1 | ADJ | Analog | Output Voltage Adjust Pin — connect resistor divider between ADJ and VO to set output voltage; V_out = 1.25V × (1 + R2/R1); bypass with 10µF capacitor to VO for ripple rejection |
| 2 | VO | Power | Regulated Output Voltage |
| 3 | VI | Power | Unregulated Input Voltage |
