Note 1. Exceeding the absolute maximum rating may damage the device.
Note 2. The device is not guaranteed to function outside its operating rating.
Note 3. Devices are ESD sensitive. Handling precautions recommended.

Note 7:
Full Load current is defined as 3A for the MIC29310/29312. For testing, VOUT 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 VOUT + 1V applied
to VIN.
For this test, VIN is the larger of 8V or VOUT + 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 8: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 9: VREF ≤ VOUT ≤ (VIN – 1V), 2.4V ≤ VIN ≤ 16V, 10mA < IL ≤ IFL, TJ ≤ TJ(max).
Note 10: VEN ≤ 0.8V and VIN ≤ 8V, VOUT = 0.
Note 11: Specification for packaged product only.
