Notes:
The absolute maximum ratings are values, which must not individually be exceeded, and furthermore, no two
of which may be realized at the same time.
1. The input and output voltage ratings may be exceeded even if the input and output clamp-current ratings are
observed.
2. The maximum package power dissipation was calculated using a junction temperature of 150°C.
