Line and Load regulation are guaranteed up to the maximum power dissipation of 1.2 W. Power dissipation is determined by the input/output differential
Dropout voltage is specified over the full output current range of the device.
See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. For guaranteed specifications and test conditions, see the
Minimum load current is defined as the minimum output current required to maintain regulation. When 1.5V
