Note:

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

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.

3. This device does not contain a thermal shutdown circuit so care should be taken not to exceed the stated

maximum power dissipation rating.Maximum power dissipation, for the SOT23 and SOT89 packages, is

calculated assuming that the device is mounted on a ceramic substrate measuring 15 x 15 x 0.6mm.
