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. Devices are ESD sensitive. Handling precaution recommended.

Note 3. The device is not guaranteed to function outside its operating conditions.

Note 4. θJA is measured in the natural convection at TA = 25°C on a high effective thermal conductivity test board (4 Layers,

2S2P) of JEDEC 51-7 thermal measurement standard. The case point of θJC is on the expose pad for SOP-8 (Exposed

Pad) package.

Note 5. VOUT2 Standby current is the input current drawn by a regulator when the output voltage is disabled by a shutdown

signal on REFEN pin (VIL < 0.2V). It is measured with VIN2 = VCNTL = 5V.

Note 6. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.

Note 7. Regulation is measured at constant junction temperature by using a 5ms current pulse. Devices are tested for load

regulation in the load range from 0A to 2A.

Note 8. VOS offset is the voltage measurement defined as VOUT subtracted from VREFEN.
