Absolute maximum V_I = 35 V (for V_O = 5 to 18 V variants) or 40 V (for 20/24 V variants). A 0.33 uF ceramic input capacitor is recommended close to the pin for stability. |+| 2 | GROUND | power_in | Common ground reference. Also serves as the thermal path via the mounting tab on TO-220/TO-220FP/DPAK/D2PAK packages (tab is electrically connected to GROUND). |+| 3 | OUTPUT | power_out | Regulated +24 V DC output, up to 1.5 A with adequate heatsinking.
