Full Load current (I

Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with

(nominal) + 1V. For example, use V
IN
= 4.3V for a 3.3V regulator or use 6V for a 5V regulator. Employ pulse
testing procedures to minimize temperature rise.
Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current
plus the ground pin current.
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a 200mA load pulse at V
IN
= 20V (a 4W pulse) for T = 10ms.

When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be
