Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Mount on a glass epoxy circuit board of 30x30mm Pad dimension of 50mm2

Notes: 1. When the positive input at ICTRL is lower than -151mV, and the voltage is decreased by 1mV, the sinking
current at the output OUT will be increased by 8mA.
2. The internal voltage reference is set at 1.240V (bandgap reference). The voltage control loop precision
takes into account the cumulative effects of the internal voltage reference deviation as well as the input
offset voltage of the trans-conductance operational amplifier.
3. If the voltage on B +Input (the positive input of the amplifier) is higher than the negative amplifier input
(VREF(B) = 1.240V), and it is increased by 1mV, the sinking current at the output OUT will be increased by
3mA.
