Note 1: Limits is 100% production tested at T
A
= +25°C. Low duty pulse techniques are used during test to maintain junc-
tion temperature as close to ambient as possible.
Note 2: Guaranteed by line regulation test.
Note 3: Adjustable mode only.
Note 4: Not tested. For design purposes, the current limit should be considered 400mA minimum to 650mA maximum.
Note 5: The dropout voltage is defined as (V

is 100mV below the target value of V
