6.5 Electrical Characteristics
At T_A= –40°C to 125°C, V_IN = V_OUT(NOM) + 0.5 V or V_IN = 3 V (whichever is greater), V_EN = V_IN, I_OUT = 10 µA, C_IN = 1 μF, C_OUT = 2.2 μF, and
FB tied to OUT, unless otherwise noted.

(1) 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.
(2) I_FB > 0 flows out of the device.
