Working Principles

The working principles of the S-1132B46-M5T1G are based on the Linear Regulatoring Principle, which requires two power supply nodes – an input node that provides the power and an output node which supplies the desired output voltage. The input current is limited, so that the power supply is not overloaded, and the output currents are held to the desired levels.

The linear regulator works by placing a power transistor between the input and output. This transistor acts as a variable voltage divider that adjusts the output voltage in proportion to the control voltage applied to its gate terminal. When the desired output voltage is attained, the transistor starts dissipating power as heat, causing the output voltage to decrease.

The power management integrated circuit (PMIC) provides various protection features that are required for proper operation, including thermal shutdown, over-voltage protection, under-voltage lockout, current limit and over-temperature protection. Additionally, these ICs offer high accuracy temperature compensation, which helps maintain voltage stability over varying temperature conditions.
