The AP1152ADU40 is a linear voltage regulator designed for modern, portable applications such as cell phones, tablets, and embedded systems. This device is part of Analogic\'s PMIC (Power Management Integrated Circuits) voltage regulator family and is designed for ultra low standby current operation, enabling the device to be used in battery-powered applications in which very little power is available. The AP1152ADU40 is also very energy efficient, with a low quiescent current of 17μA, making it suitable for battery-operated applications.

The AP1152ADU40 is a low voltage (1.2V to 5.0V) linear regulator designed to supply up to 300mA of output current. It is capable of dropping the input voltage down to 0.7V below the output voltage. The AP1152ADU40 is a dual-channel, adjustable device with two independent output voltage pins, allowing for both positive and negative output voltage options. One pin also allows for an adjustable output voltage, for use in applications requiring a changeable output voltage. The AP1152ADU40 is designed to provide clean output power, with no need for additional external components. Its low noise and low output ripple make it suitable for high precision applications, such as digital and audio equipment.

The AP1152ADU40 is built on a CMOS process and packaged in a SOT26 (8-lead). This package offers high circuit density and maximum thermal performance. The operating temperature range of this device is -40°C to 85°C, while the storage temperature range is -45°C to 125°C. It has an input voltage of between 1.2V and 7.0V, an output voltage of between 0.9V and 5.5V, and a current output of up to 300mA.

The AP1152ADU40 is designed for a wide range of applications, such as:

• Cell phones
• Tablets
• Digital audio equipment
• GPS systems
• Automotive electronics
• Measuring and instrumentation systems

The AP1152ADU40 is designed with a current limit and thermal overload protection to ensure its reliable performance. It also incorporates an enable pin which allows the user to shut down the device in low power applications. The AP1152ADU40 has a high power dissipation capability making it suitable for applications in which minimal heat dissipation is required.

The working principle of the AP1152ADU40 is based on the same basic principle as all other linear voltage regulators. It works by using an internal resistor network to adjust the input voltage. The input voltage is compared to a fixed reference voltage. The difference between these two voltages is applied to the resistor network, which adjusts the output voltage to match the reference voltage. This is known as the “linear regulation” method of voltage regulation.

The AP1152ADU40 is designed to be used in a wide range of applications from cell phones and tablets, to automotive electronics and measuring and instrumentation systems. It offers a small footprint and low power consumption, making it suitable for battery operated applications. Furthermore, its dual-channel, adjustable output voltage capability and its integrated current limit and thermal overload protection make it suitable for a range of precision applications.
