(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 heatsinking.

(2)

IFB > 0 flows out of the device.

6.5 Electrical Characteristics

At TA= –40°C to 125°C, VIN = VOUT(NOM) + 0.5 V or VIN = 3 V (whichever is greater), VEN = VIN, IOUT = 10 µA, CIN = 1 μF, COUT = 2.2 μF, and

FB tied to OUT, unless otherwise noted.
