(VIN - VOUT) = 3V, IOUT = 10mA
Notes:
1. Low duty cycle pulse testing with which TJ remains unchanged.
2. 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 98% from the nominal
value obtained at VIN = VOUT +2V.
