The device is also suitable for applications where low power dissipation is critical, such as automotive and industrial systems. The basic working principle of this voltage regulator is simple. The input voltage is compared to a voltage reference. If the input voltage exceeds the reference voltage, the regulator output is turned off. If the input voltage is below the reference, then the regulator output is turned on. The output voltage is determined by a resistive divider network, which is connected to the reference. The resistors in the divider network can be adjusted to set the output voltage at a desired level.In addition, this linear voltage regulator also features a current limit and thermal shutdown protection. In current limit mode, the device will limit the output current to a safe level. This protects components from being damaged due to excessive current draw. In thermal shutdown mode, the device will turn off the output voltage if the temperature gets too high, protecting the device from overheating.
