Note 1. Low duty cycle pulse tested with Kelvin connections.
Note 2. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
Note 3. Bandwidth of 10 Hz to 10 kHz.
Note 4. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard. The case point of θJC is on the center of the exposed pad.
