Working Principle

ISL80138IVEAJZ-T7A Voltage Regulator is designed to operate with a constant output voltage despite varying input voltages and load currents. The device consists of an output voltage feedback divider, error amplifier, reference voltage generator, overvoltage comparator, power switch, current limit circuit, and open-drain output buffer. When input voltage exceeds the preset value, the output voltage will remain constant, resulting in a regulated output voltage.The working principle of ISL80138IVEAJZ-T7A Voltage Regulator is based on two key components: the power switch and error amplifier. The power switch is the heart of the voltage regulator and is responsible for controlling the amount of current flowing through the device. The error amplifier is used to compare the feedback voltage from the feedback divider with the programmed reference voltage. The difference or error is then amplified and used to control the switching speed and on-off proportion of the power switch. This helps to maintain a stable regulated output voltage.
