V_IN = 2.8V to 5V
V_IN ≥ 2.8V, I_OUT = 200mA
By I²C Setting
I_OUT = 1mA
V_IN = (V_OUT + 0.3V) to 5V or
V_IN > 2.5V, whichever is larger
1mA < I_OUT < 200mA
R_LOAD = 1Ω

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA = 25°C on a high effective thermal conductivity four-layer test board of
JEDEC 51-7 thermal measurement standard.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
