6.5 Electrical Characteristics
At TJ = –55°C to 125°C, VIN = VOUT(NOM) + 2 V or VIN = 7 V (whichever is greater), VEN = VIN, IOUT = 100 µA, CIN = 1 μF, COUT = 4.7 μF, and
FB tied to OUT, unless otherwise noted.

(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
≈ (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 heatsinking.
(3)
IFB > 0 flows out of the device.
(4)
CBYP refers to a bypass capacitor connected to the FB and OUT pins.
