Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

220°C/W, and the MIC5206-x.xBMM (all versions) is 200°C/W, mounted on a PC board (see “Thermal Considerations” for further details).

4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.

5. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range

from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.

6. Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1Vdifferential.

7. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load

current plus the ground pin current.

8. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line

9. The error flag comparator includes 3% hysteresis.
