ELECTRICAL CHARACTERISTICS
(VIN = VOUT+0.5V or 2.5V, CIN = COUT = 2.2μF, EN1=EN2=VIN, TA= 25°C, for each LDO unless otherwise specified)
Notes：1. Limits beyond which damage to the device may occur is indicated by absolute maximum ratings.
Conditions for which the device is intended to be functional is indicated by operating ratings, but specific
performance` limits isn’t be guaranteed. Only for the test conditions listed the guaranteed specifications
can be applied. When the device is not operated under the listed test conditions some performance
characteristics may degrade.
2. Which discharged through a 1.5kΩ resistor into each pin is a 100pF capacitor in the human body model.
3. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
