Note 1. Fixed output voltage version only.
Note 2. Adjustable output voltage version only.
Note 3. Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the input line
voltage. Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in load
current.
Note 4. Regulation is measured at constant junction temperature by using a 10ms current pulse. Devices are tested for load regulation in
the load range from 10mA to 3.0A.
Note 5. For V
OUT
≤ 1.0V, the V
BIAS
Dropout specification does not apply due that the minimum V
BIAS
input is 3.0V.
Note 6. I
GND
= I
BIAS
+ (I
IN
– I

). The total current drawn from the supply is the sum of the load current plus the ground current.
