Notes:
4. 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.
5. 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.
6. Maximum power dissipation for the SOT23 package, is calculated assuming that the device is mounted on a ceramic substrate measuring
15x15x0.6mm.
