Working Principle

The S-1165B46MC-N7FTFG is a linear voltage regulator. This means that its output voltage is regulated by varying the current drawn from the input voltage. In essence, the device acts as a resistive element across the input-output nodes.When the input voltage increases, the output voltage increases until it reaches the maximum rated voltage. When the input voltage decreases, the ‘ON’ resistance of the device increases and the output voltage decreases.The ‘ON’ resistance of the S-1165B46MC-N7FTFG is controlled using a special biasing circuit. This allows for a very low dropout voltage and tight output voltage regulation.
