The AP1115AY18G-13 is a linear voltage regulator module consisting of a three-terminal adjustable or fixed output voltage regulator and an output low-pass filter, designed for use in a wide range of applications. It is based on a bandgap voltage reference for stable output.

The AP1115AY18G-13 is available in three voltage classes: 1.8V, 2.5V, and 3.3V. All three voltages are adjustable via an external resistor divider, with a standard tolerance of ±1%. Additionally, the AP1115AY18G-13 voltage regulator also features a dynamic output voltage over-current limiting, and thermal shutdown protection.

The main application field of the AP1115AY18G-13 linear regulator module is in communications and networking, industrial, and consumer electronics. It is suitable for use in power supply systems, power management, system power sequencing, and power supply protection functions, providing an extended operating temperature range of -20°C to +85°C.

The AP1115AY18G-13 voltage regulator module can operate in a wide range of input and output voltage ranges, including a maximum input voltage of 8.0V, and an output voltage of up to 3.3V, with a minimum operating current of 1mA. Its low dropout voltage and fast transient response, achieved through a patented circuit topology, make the AP1115AY18G-13 voltage regulator suitable for use in audio, video, and communication applications. Additionally, its low noise and ripple levels, fast transient response and tight load regulation specification, make it ideal for use in battery protection circuits, DC/DC step-down converters, and power supplies for sensitive analog and digital signals.

The working principle of the AP1115AY18G-13 voltage regulator is based on a bandgap voltage reference. The module features a three-terminal adjustable or fixed output voltage regulator, with an output low-pass filter for stability. The input voltage is regulated by adjusting the output voltage level. The voltage regulator module has an adjustable threshold voltage, which is set through the use of an external resistive divider. This allows it to maintain a stable output, and ensures that it can be used in a wide range of voltage and current ratings. When the input voltage exceeds the threshold voltage, the module reduces its output voltage to maintain the output voltage within the specified range. In the event of an over-current situation, the AP1115AY18G-13 voltage regulator will shut down and an over-current indicator will be illuminated.

The AP1115AY18G-13 is a highly-efficient linear voltage regulator module that is ideal for use in a range of applications, from communications and networking, to industrial and consumer electronics. It features a wide range of features, including an adjustable output voltage, low dropout voltage, and fast transient response. The module also features a low noise and ripple level, along with thermal and over-current protection. The module is highly reliable, and its wide operating temperature range ensures that it can be used in any application.
