Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended.
4. The maximum allowable power dissipation at any T A (ambient temperature) is P D(max) = (T J(max) – T A ) ÷ θ JA . The θ JC of the MIC5231 is 130°C/W.
Mounted to a standard PC board, the θ JA is approximately 235°C/W.
5. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
6. Regulation is measured at constant junction temperature using low duty cycle pulse testing.
7. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1Vdifferential.
For outputs below 3.5V, dropout voltage is the input-to-output differential with the minimum input voltage 3.5V. Minimum input operating voltage is
3.5V.
