1) If the voltage on VCTRL (the negative input of the amplifier) is higher than the positive amplifier input
(Vref = 1.210V), and it is increased by 1mV, the sinking current at the output OUT will be increased by 3.5mA.
2) The internal voltage reference is set at 1.210V (band-gap 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. The internal voltage reference is fixed by band-gap, and trimmed to 0.5%
accuracy at room temperature.
3) When the positive input at ICTRL is lower than -100mV, and the voltage is decreased by 1mV, the sinking
Current at the output OUT will be increased by 7mA.
4) The internal current sense threshold is set to -100mV. The current 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-conduction operational
amplifier.
