Doc ID 2147 Rev 13

Note:

The circuit of Figure 19 can be modified to provide supply protection against short-circuits

by adding a short-circuit sense resistor, RSC, and an additional PNP transistor. The current

sensing PNP must be able to handle the short-circuit current of the three-terminal regulator.

Therefore, a four ampere plastic power transistor is specified.
