(1) To ensure stability at no-load conditions, a current from the feedback resistive network greater than or equal to 10 µA is required.

(2) Maximum input voltage is limited to 24 V because of the package power dissipation limitations at full load (P ≈ (V_IN – V_OUT) × I_OUT = (24 V – V_REF) × 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 heatsinking.

(3) I_FB > 0 flows out of the device.

(4) C_BYP refers to a bypass capacitor connected to the FB and OUT pins.
