Hysteresis

Notes:

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

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

3. The maximum allowable power dissipation of any TA (ambient temperature) is (PD(max) = TJ(max) – TA) / θJA. Exceeding the maximum allowable power

dissipation will result in excessive die temperature and the regulator will go into thermal shutdown.

4. Specification for packaged product only.

5. Minimum input for line regulation test is set to VOUT + 1V relative to the highest output voltage.

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.

For outputs below 1.65V, dropout voltage is considered the input-to-output voltage differential with the minimum input voltage of 1.65V. Minimum

input operating voltage is 1.65V.
