a 1.2V to 37V output range.

This is exceptionally easy to use and require only two

external resistors to set the output voltage.

Further, it employ internal current limiting, thermal

shutdown and safe area compensation.

Ci is required when regulator is located an appreciable distance from power supply filter.

Co is not needed for stability, however, in the range of 1μF to 100μF of aluminum or tantalum

electrolytic are commonly used to provide improved output impedance and rejection of transients.

Since I_Adjis controlled to less then 100μA , the error associated with this term is negligible in most applications.
