Notes: The absolute maximum ratings are values, which must not be 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. This value is limited to 5.5 V maximum.
3. The data above are measured by ∆V_BE method mounting on glass epoxy board (40 × 40 × 1.6 mm) with 10%
of wiring density.
