This feature helps save energy and extends the life of the chip by only using power when it is needed. The shutdown control pin allows the user to manually shutoff the chip as needed.

Working Principle

An AP1118S18L-13 linear voltage regulator works by using a voltage reference and series pass transistor to regulate its output voltage. The voltage reference determines the output voltage and the series pass transistor acts as a switch, allowing the current to pass when the output voltage is within specification.The chip can also utilize a voltage divider network composed of resistors to provide a feedback signal to the chip. When the output voltage is lower than the set voltage, the feedback signal causes current to pass through the series pass transistor, allowing the voltage to increase. When the output voltage is higher than the set voltage, the current is switched off, thus decreasing the output voltage.The AP1118S18L-13 has internal current limiting and over-temperature protection features to ensure that the device does not overheat or draw too much current. It also allows for both fixed and adjustable voltage outputs, making it an ideal choice for a variety of applications.
