Working Principles

The LT6005CDHC#PBF operates as a linear voltage regulator. It uses a pass transistor to regulate the output voltage based on the difference between the input and desired output voltage. The adjustable output voltage is achieved by setting the voltage at the ADJ pin using external resistors.

When the input voltage is higher than the desired output voltage, the pass transistor conducts and regulates the output voltage to the desired level. In case of excessive heat buildup, the thermal shutdown protection activates, turning off the pass transistor to prevent damage.
