Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits

and associated test conditions, see the Electrical Characteristics tables.

(2)

All voltages are with respect to the potential at the GND pins. The LM3212 is designed for mobile phone applications where turn-on after

power-up is controlled by the system controller and where requirements for a small package size overrule increased die size for internal

Under Voltage Lock-Out (UVLO) circuitry. Thus, it should be kept in shutdown by holding the EN pin low until the input voltage exceeds

2.7V.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

The Human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. (MIL-STD-883 3015.7) The machine

model is a 200 pF capacitor discharged directly into each pin.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper ESD

handling procedures can result in damage.
