Functional linear voltage regulators are some of the core components of every electronic device, from smartphones and computers to microphones, TVs, and gaming consoles. AP1118S12L-13 is a robust and efficient linear voltage regulator with a voltage range of 4.5V to 13.2V. It is a powerful voltage regulator that combines high accuracy, low quiescent current, and fast line and load regulation.

The output current of AP1118S12L-13 is rated at 1.5A. Its high efficiency, low dropout voltage, and low quiescent current makes it suitable for use in various applications including notebooks, tablets, digital media players, broadband equipment, set-top box, modems, routers, and PDAs.

AP1118S12L-13 operates with an input voltage range of 4.5V to 13.2V, and provides a fixed output of 12V in the 0 to 13.2V input voltage range. It also provides a fixed output voltage of 11.5V in the 0 to 4.5V input range. The linear voltage regulator features a fast transient response and can meet the requirements of extremely low in-rush current.

The AP1118S12L-13 is controlled using a two-stage system with a positive output voltage reference and a constant output voltage feedback. The positive voltage reference is generated using an internal voltage divider so that it can be set accurately. The output voltage also has an error amplifier, which is used to calculate the output voltage difference between the input voltage and the given reference voltage. This error then determines the current required to drive the output voltage to the reference voltage. The error amplifier also serves as an amplifier for the noise rejection circuit and for current limiting.

The AP1118S12L-13 is built with protection against overloads, short circuit, and under-voltage, making it an ideal choice for critical applications. It features an Over Temperature Shutdown (OTSD) function to protect the output voltage during peak power demand. It also has an Under Voltage Lock Out (UVLO) function to protect the circuits that require a certain input voltage level and provides higher efficiency and improved power factor in the Long Life Mode. The device has an adjustable thermal shutdown temperature, which can be set by an external resistor. It also offers an I2C interface, which allows programming and control of the output voltage and the external transistor.

The AP1118S12L-13 is a robust and high-performance linear voltage regulator, which is suitable for a wide range of applications. Its high efficiency, low quiescent current, fast line and load regulation, and various protection functions make it a powerful and reliable voltage regulator for various electronic devices.
