Ground Pin
Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.
Full Load current is defi ned as 3A for the MIC29310/29312. For testing, V
Dropout voltage is defi ned as the input-to-output differential when the output voltage drops to 99% of its nominal value with V
to V
For this test, V
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 coeffi cient is defi ned as the worst case voltage change divided by the total temperature range.
