Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are ensured through cor-

relation using Statistical Quality Control (SQC) methods.

2: Validated by line regulation test.

3: Not tested. For design purposes, the current limit should be considered 150 mA minimum to 410 mA maximum.

4: The dropout voltage is defined as (VIN – VOUT) when VOUT is 100 mV below the value of VOUT for

VIN = VOUT +2V.
