Working Principle

The AP1184K5-L-13 is a three-terminal adjustable voltage regulator. It has an input voltage of up to 30V and can produce a stable output voltage ranging from 1.25V to 13V. The device incorporates a resistive divider from the output to the reference terminal. The output voltage of the regulator is then determined by the ratio of resistors used in this divider.

The device also employs a P-Channel MOSFET internally, which increases the efficiency of the unit and provides a low-dropout performance. The MOSFET is controlled by an error amplifier, which maintains the output voltage at a pre-set level. The output of this amplifier is also connected to a bandgap reference, which adjusts the voltage as per any changes in the input voltage. This ensures that the output voltage remains stable even at a wide range of input voltages.

The AP1184K5-L-13 provides additional features such as thermal shutdown, current limit and output over-voltage protection, which makes it suitable for use in a wide range of applications.
