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.

required to set the output voltage to a value higher than 0.69 V. See the Electrical Characteristics table.
B. An additional 22-μF ceramic input capacitor is recommended to reduce RMS ripple current.
C. For V
I
greater than 8V, the minimum required C

may be reduced to 220 μF plus a 22-μF ceramic capacitor.
D. 100 μF of output capacitance can be achieved by using two 47-μF ceramic capacitors .
