Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through cor-
relation using Statistical Quality Control (SQC) Methods.
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 120mA minimum to 420mA maximum.
Note 5: The dropout voltage is defined as (VIN - VOUT) when VOUT is 100mV below the value of VOUT for VIN = VOUT +2V.
