Electrical Characteristics (Continued)

AP2111-4.8 Electrical Characteristic (Note 2) (Only for SOT-223)

unless otherwise specified (Note 3).

Note 2: To prevent the short circuit current protection feature from being prematurely activated, the input voltage

must be applied before a current source load is applied.
