Working Principles

The ISL9012IRPLZ Linear Voltage Regulators work on the principle of current control. They control the output voltage by controlling the current through a sense resistor. The output voltage is proportional to the current flowing through the resistor. The current is monitored by the regulator and compared to the voltage set by the use of a reference voltage. If the voltage set by the reference is higher than the output voltage, the regulator will increase the current until the two are equal. If the voltage set by the reference is lower than the output voltage, the regulator will decrease the current until the two are equal. When the two voltages are equal, the regulator will maintain the output voltage constant.
