Table 5: Electrical Characteristics Of LD29080#15

(IO = 10mA (Note 4), TJ = 25°C, VI = 3.5V, VINH = 2V, 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: Reference Voltage is measured between output and GND pins, with ADJ PIN tied to VOUT.

NOTE 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 2mA is required.
