(1) Maximum input voltage is limited to 24 V because of the package power dissipation limitations at full load (P ≈ (VIN – VOUT) × IOUT =
(24 V – VREF) × 50 mA ≈ 1.14 W). The device is capable of sourcing a maximum current of 50 mA at higher input voltages as long as the power dissipated is within the thermal limits of the package plus any external heat sinking.
(2) IFB > 0 flows out of the device.
