1. Temperature variations are included within the output voltage accuracy.
2. Guaranteed by design.
3. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100mV below its nominal
value (does not apply to input voltages below 2.5V).
4. EN must be driven with a t
R = tF < 10ms.
5. Turn on time is time measured between the enable input just exceeding the V
EN high value and the output volt-
age just reaching 95% of its nominal value.
6. Typical thermal protection hysteresis is 20ºC.
Note: All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or
SQC (Statistical Quality Control) methods.
