Note 2: Limits are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed through cor-
relation using Statistical Quality Control (SQC) Methods.
Note 3: Guaranteed by line regulation test.
Note 4: Adjustable mode only.
Note 5: Not tested. For design purposes, the current limit should be considered 120mA minimum to 420mA maximum.
Note 6: The dropout voltage is defined as (V
IN
- V
OUT
) when V
OUT
is 100mV below the value of V
