Notes:
1. Low duty cycle pulse testing with which T
J
remains unchanged.
3. The dropout voltage is the input/output differential at which the circuit ceases to regulate against further
reduction in input voltage. It is measured when the output voltage has dropped 2% from the nominal value
obtained at V
