Note 1: Guaranteed by line regulation test.
Note 2: Adjustable mode only.
Note 3: Not tested. For design purposes, the current limit should be considered 120mA minimum to 320mA maximum.
Note 4: The dropout voltage is defined as (VIN_ - VOUT_) when VOUT_ is 100mV below the value of VOUT_ for VIN_ = VOUT_ +2V.
Note 5: Specifications to -40°C are guaranteed by design and not production tested.
