Working Principle of AS1358-BTTT-25

The working principle of the AS1358-BTTT-25 is mainly based on the process of linear regulation. Basically, when the output voltage is unstable and there is a change in the input voltage, the cores of this regulator will internally adjust the output voltage to maintain stability. When the input voltage is higher than the nominal output voltage, the cores of the regulator will absorb excess power, turning it into heat and dissipating it through the heatsink. Conversely, when the input voltage is lower than the nominal output voltage, the cores will supply additional power to the output.

The AS1358-BTTT-25 uses a wide range of electronic components, including a high precision comparator, a sample and hold circuit and an operational amplifier circuit, to manage the current. It also uses some advanced techniques to take into account the various interface loads, such as start-up time, frequency of operation, and response time. By analyzing the various interface loads, the linear voltage regulator is able to regulate the output voltage for any small changes in the input voltage.
