4V to 72V Input LDOs with Boost Preregulator
ELECTRICAL CHARACTERISTICS (continued)
(VIN = VEN = 14V, IOUT = 1mA, CIN = 47µF, CBSOUT = 22µF, COUT = 10µF, CVL = 1µF, TA = TJ = -40°C to +125°C, unless otherwise
noted. See Figures 4–7 as applicable. Typical specifications are at TA = +25°C.) (Note 2)

Note 2: Limits at -40°C are guaranteed by design and characterization; not production tested.
Note 3: Guaranteed minimum operating voltage is 3.5V on VIN falling only.
Note 4: Guaranteed by design and not production tested.
Note 5: The continuous maximum output current from the LDO is guaranteed according to the maximum power dissipation imposed
by the package thermal constraints.
Note 6: Maximum output adjustable value is conditioned by the maximum adjustable BSOUT Output Voltage Range minus the maxi-
mum dropout across the pass transistor.
Note 7: Dropout voltage is defined as (VBSOUT - VOUT) when VOUT is 2% below the value of VOUT for VBSOUT = VOUT + 2V.
