ELECTRICAL CHARACTERISTICS
(1) (2)
Unless otherwise noted, VEN = 950 mV, VIN = VOUT + 1.0V, or 2.0V, whichever is higher, where VOUT is the higher of VOUT1 and
VOUT2. CIN = 1 µF, IOUT = 1 mA, COUT1 = COUT2 = 1.0 µF.
Typical values and limits appearing in normal type apply for TA = 25°C. Limits appearing in boldface type apply over the full
junction temperature range for operation,
−40 to +125°C.

(1)
All Voltages are with respect to the potential at the GND pin.
(2)
Min and Max limits are specified by design, test or statistical analysis. Typical numbers are not ensured, but do represent the most likely
norm.
(3)
VIN(MIN) = VOUT(NOM) +0.5V, or 2.0V, whichever is higher.
(4)
Dropout voltage is voltage difference between input and output at which the output voltage drops to 100 mV below its nominal value.
This parameter only for output voltages above 2.0V
