ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings(†)

Supply Voltage (VIN1, VIN2).......................................................................................................................... –0.3V to +6V

Enable Voltage (VEN1, VEN2) .........................................................................................................................–0.3V to VIN

Power Dissipation (PD) Note 1...............................................................................................................Internally Limited

ESD Rating Note 2..................................................................................................................................................... 3 kV

Operating Ratings(‡)

Supply Voltage (VIN1, VIN2)....................................................................................................................... +2.5V to +5.5V

Enable Voltage (VEN1, VEN2) ..............................................................................................................................0V to VIN

Note 1: 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.

2: Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 kΩ in series

with 100 pF.

† 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 con-

ditions 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.
