4 Electrical characteristics
I
O
= 10 mA, (Note 4) T
J
= 25 °C, V
I
= 3.5 V, V
INH
= 2V, C
I
= 330 nF, C
O
= 10 µF, unless
otherwise specified.
Note: 1 Guaranteed by design.
2 Dropout voltage is defined as the input-to-output differential when the output voltage drops
to 99% of its nominal value with V
O
+ 1 V applied to V
I
.
3 Reference voltage is measured between output and GND pins, with ADJ PIN tied to V
O
.
4 In order to avoid any output voltage rise within the whole operating temperature range, due
to output leakage current, a minimum load current of 2 mA is required.
