Electrical characteristics

IO = 10 mA, TJ = 25 °C, VI = 3.8 V, VINH = 2 V (Note 3), CI = 330 nF, CO = 10 µF, unless

otherwise specified.

Note:

Guaranteed by design.

Dropout voltage is defined as the input-to-output differential when the output voltage drops

to 99% of its nominal value with VO + 1 V applied to VI.

Only for version with Inhibit function.
