ELECTRICAL CHARACTERISTICS
Notes:
1. The maximum operating input voltage and output
current of the device will be governed by the
maximum power dissipation of the selected package.
Maximum package power dissipation is specified at
25 °C and must be linearly derated to zero at
Tamb=125°C.
2. The following data represents pulse test conditions
with junction temperatures as indicated at the
initiation of the test. Continuous operation of the
devices with the stated conditions might exceed the
power dissipation limits of the chosen package.
Power Dissipation (Tamb=25°C)
SOT223
2W(Note 3)
TO92
600mW
3. Maximum power dissipation for the SOT223 and
SO8 packages, is calculated assuming that the device
is mounted on a PCB measuring 2 inches square.
4. The shut down feature of the device operates if its
temperature exceeds its design limit as might occur
during external faults, short circuits etc. If the
regulator is supplied from an inductive source then a
large voltage transient, on the regulator input, can
result should the shut down circuit operate. It is
advised that a capacitor (1
F or greater) should be
applied across the regulator input to ensure that the
maximum voltage rating of the device is not
exceeded under shutdown conditions.
