ILIM = Selected current limit value
V = Regulated output voltage
OUT
R = Externally programmable current limit resistor.
LIM
Accuracy of the current limit setting is better than ±20% over full operating temperature range.
*Internal ESD structure. In cases where EN is permanently tied to V , it’s recommended that a 10-20k
IN
resistor should be inserted in the link between EN and VIN.
