Total Current Consumption
Note:
1: If the Voltage on Vctrl (the negative input of the amplifier) is higher than the positive amplifier input (Vref-1.21V), and
it is increased by 1mV, the sinking current at the output will be increased by 3.5mA.
2: The internal Voltage reference is set at 1.21V (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. The internal voltage reference is fixed by bandgap, and trimmed to 0.5%
accuracy at room temperature.
3: When the positive input at Ictrl is lower than -200mV, and the voltage is decreased by 1mV, the sinking current
at the output will be increased by 7mA
4: The internal current sense threshold is set to -200mV. 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
