While the maximum recommended value of RILIM is 232 k
, there is one additional configuration that allows for
a lower current-limit threshold. The ILIM pin may be connected directly to IN to provide a 75 mA (typ) current-limit
threshold. Additional low-ESR ceramic capacitance may be necessary from IN to GND in this configuration to
prevent unwanted noise from coupling into the sensitive ILIM circuitry.
