This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1)

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

All voltages are with respect to the potential at the GND pins. The LM3253 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.

(5)

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.
