LDO1, 2, and 3 Electrical Characteristics
(1)(2) (continued)
Limits in standard typeface are for TA = TJ = 25°C. Limits in boldface type apply over the full operating ambient temperature
range (
−30°C ≤ TA = TJ ≤ +85°C). Unless otherwise noted, specifications apply to the LM3280 with: VIN = 3.6V, ENBUCK =
3.6V, BYP = 0V, FB = 2V, VCON = 0.267V, ENLDOx = 3.6V
(3).

The current is defined as the load current at which the LDOx voltage is 1.0V lower than the nominal output voltage.
(5)
Dropout voltage is the voltage difference between the input and the output at which the output voltage drops to 100mV below the
nominal voltage.
LDO1, 2, and 3 System Characteristics
(1)
The following spec table entries are guaranteed by design if the component values in the typical application circuit are used.
Unless otherwise noted, specifications apply to the LM3280 with: VIN = 3.6V. These parameters are not guaranteed by
production testing.
