Note 5:
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.
Note 6: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 7: V_REF ≤ V_OUT ≤ (V_IN – 1 V), 2.4V ≤ V_IN ≤ 16V, 10mA < I_L ≤ I_FL, T_J ≤ T_{J MAX.}

Note 8: V_EN ≤ 0.8V and V_IN ≤ 8V, V_OUT = 0.
