(V_IN - V_OUT) = 3V, I_OUT = 100mA
Notes:
1. Low duty cycle pulse testing with which T_J remains unchanged.
2. The I_Q of SE8117BT15 is 1.2mA(Typ.)
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 98% from the nominal
value obtained at V_IN = V_OUT +1.5V.
