4 / 9 page MIC2211 Micrel M9999-090204 4 August 2004 Electrical Characteristics(4) V IN = VOUT +1.0V for higher output of the regulator pair; COUT = 1.0µF, IOUT = 100µA; TJ = 25°C, bold values indicate –40 °C ≤ T J ≤ +125°C; unless noted. Parameter Conditions Min Typ Max Units Output Voltage Accuracy Variation from nominal V OUT –1.0 +1.0 % –2.0 +2.0 % Output Voltage Temp.

Exceeding maximum rating may damage the device. 2. The device is not guaranteed to work outside its operating rating. 3. The maximum allowable power dissipation of any T A (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 V OUT + 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 differen- tial. For outputs below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.25V. Minimum input operating voltage is 2.25V.
