Working Principles
The ISL6140IB operates as a linear voltage regulator. It takes an input voltage within the specified range and regulates it to provide a stable output voltage. The feedback pin (FB) is used to adjust the output voltage by connecting an external resistor divider network. The enable pin (EN) controls the on/off state of the regulator. When enabled, the IC regulates the input voltage to maintain the desired output voltage. If the temperature rises excessively or an overcurrent condition occurs, the regulator activates the thermal shutdown and overcurrent protection mechanisms, respectively.
