ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings †

Supply Voltage (VIN) .................................................................................................................................... –0.3V to +6V

Enable Voltage (VEN) .................................................................................................................................... –0.3V to VIN

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

ESD Rating (Note 2) ..................................................................................................................................................3 kV

Operating Ratings ‡

Supply Voltage (VIN) ................................................................................................................................. +2.5V to +5.5V

Enable Voltage (VEN) ......................................................................................................................................... 0V to VIN

† 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: 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 reg-

ulator 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.
