Operating Ratings ††

Supply Voltage (VIN)................................................................................................................................+1.65V to +5.5V

Power Dissipation (Note 2).....................................................................................................................Internally Limited

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.

†† Notice: The device is not guaranteed to function outside its operating ratings.

Note 1: Specification for packaged product only.

2: 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.

Note 1: Specification for packaged product only.

2: VR is the nominal regulator output voltage when the input voltage is VIN = VOUT + 1V or VIN = 1.65V

(whichever is greater).

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

4: 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 volt-

age is 1.65V.
