Note 1.

Exceeding the absolute maximum rating may damage the device. Devices are ESD sensitive. Handling precautions recommended.

Note 2.

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

Note 3.

Off is

≤ 0.8V and on is ≥ 2.4V for the MIC2529-1 switch. Off is ≥ 2.4V and on is ≤ 0.8V for the MIC2529-2 switch. The enable input has

approximately 200mV of hysteresis. See control threshold charts. Limits do not include 3VOUT load current of 100

µA during test.

Note 4.

See “Functional Characteristics: Current-Limit Response” photo.

Note 5.

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

Note 6.

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

differential.
