NOTES: (1) All operating conditions include the combined effects of load current, input voltage, and temperature over each parameter’s full specified range.
(2) Load and line regulation are tested at a constant junction temperature by low duty cycle testing. (3) Dropout voltage is defined as the minimum input-to-output
voltage that produces a 1% decrease in output voltage. (4) V
