Table 4: Electrical Characteristics Of LD29150#15
(IO = 10mA, TJ = 25°C, VI = 3.5V, VINH = 2V (Note 2), CI = 330nF, CO = 10µF, unless otherwise specified)
NOTE 1: Guaranteed by design.
NOTE 2: Only for version with Inhibit function.
Table 5: Electrical Characteristics Of LD29150#18
(IO = 10mA, TJ = 25°C, VI = 3.8V, VINH = 2V (Note 3), CI = 330nF, CO = 10µF, unless otherwise specified)
NOTE 1: Guaranteed by design.
NOTE 2: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with VO+1V
applied to VI.
NOTE 3: Only for version with Inhibit function.
