The maximum continuous supply voltage is 16V.
Full Load current is defined as 5A for the MIC29510/29512. For testing, V
OUT
is programmed to 5V.
Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with V
OUT
+ 1V applied
to V
IN
.
For this test, V
IN
is the larger of 8V or V
OUT
+ 3V.
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.
