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

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. Maximum power dissipation for the SOT23 package, is calculated assuming that the device is

mounted on a ceramic substrate measuring 15 x 15 x 0.6mm.
