AP1115AY35L-13

Introduction

AP1115AY35L-13 is a linear voltage regulator which belongs to the family of PMIC (Power Management ICs) products. It’s a highly integrated solution for providing the required power to the system, and features high efficiency level, advanced safety features, and comprehensive ESD protection over a wide operating temperature range.

Working Principle

The AP1115AY35L-13 linear regulator has as its fundamental building block a voltage reference and an error amplifier. This configuration is commonly known as a voltage regulator. The voltage reference can be an integrated circuit or a discrete component which produces a known reference voltage. The error amplifier then compares the reference voltage to an input signal. The output of the error amplifier is then routed through an error-feedback loop whose purpose is to sense any changes in the input voltage, compare it to the reference voltage and provide the required correction current to the output stage in order to keep the output voltage constant.

In addition, the linear regulator can incorporate functions such as power good, over current and over temperature protection, provide adjustable output current limit and short-circuit protection with thermal shutdown, allow for soft start and enable power up sequencing features. All the features help make the AP1115AY35L-13 an ideal choice for high-power applications.
