Notes:
General Note: Devices are ESD sensitive. Handling precautions are recommended.
1. The maximum continuous supply voltage is 16V.
2. Full Load current is defined as 5A for the MIC29510/29512. For testing, V_OUT is programmed to 5V.
3. Dropout voltage 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.
4. For this test, V_IN is the larger of 8V or V_OUT + 3V.
5. Ground pin current is regulator quiescent current. Total current drawn from the source is the sum of the load current plus the ground pin current.
6. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
7. V_REF ≤ V_OUT ≤ (V_IN – 1V), 2.4V ≤ V_IN ≤ 16V, 10mA < I_L ≤ I_FL, T_J ≤ T_{J MAX}.
8. V_EN ≤ 0.8V and V_IN ≤ 8V, V_OUT = 0.
