The FAN1655MPX is a special purpose voltage regulator integrated circuit from Fairchild Semiconductor. It is designed to provide a wide range of voltage regulation requirements within a given system while reducing design complexity.

The FAN1655MPX combines a set of low-dropout (LDO) regulators with fixed output voltages of 1.5V, 1.8V and 3.3V, with various current capacities. It also includes an adjustable high-efficiency (HE) output voltage, with adjustable values ranging from 0.8V to 3.3V, and adjustable current capacities of 1A, 2A and 3A. It has an adjustable shutoff point and an internal compensation loop. Additionally, it is built with advanced frost protection and temperature sensing to ensure it operates variably and safely within specified operating temperatures.

FAN1655MPX\'s primary application is power-management systems, providing adjustable and fixed voltage outputs to power nodes that require additional voltage inputs. It is suitable for a variety of different products, from cell phones and portable electronics to memory, peripheral and microprocessor applications. It is available in four package variants: P-DIP14, P-SIP10, P-SOP16/SOP10/SOT23-5, providing customers with greater flexibility in package selection.

The FAN1655MPX is designed to work with two basic methods: either an Internally Regulated Voltage Output (IRVO) or an Externally Regulated Voltage Output (ERVO). In the IRVO configuration, the FAN1655MPX is responsible for providing the regulated output voltage and adjusts it internally depending on the system’s needs. The ERVO configuration is used when the output voltage needs to be externally adjusted, allowing for a higher precision of voltage regulation.

The FAN1655MPX is designed to protect against the effects of extreme power transients, making it an ideal choice for mobile and other applications requiring low-power operation and low output voltage ripple. It also features thermal foldback and thermal shutdown, which shut down and foldback the output depending on temperature, helping to ensure safe and reliable operation at high temperatures and to ensure that the operating temperature of the device remains within its temperature limits when operated at high current.

The FAN1655MPX also contains a wide input voltage range of 3.6V - 20V, which makes it an ideal choice for automotive applications, consumer applications, and other applications that require a wide input voltage range. The FAN1655MPX also has a wide choice of load current, and is capable of supplying up to 1.5A, 2A and 3A of output current.

In addition, the FAN1655MPX also includes a slew rate control feature, which can be used to decrease the voltage transition time by allowing for a faster rise and fall time in the output voltage. This reduces system noise and power dissipation, which can make the FAN1655MPX more cost effective and efficient.

Overall, the FAN1655MPX is a high-performance, low-power, low-noise, low-dropout voltage regulator, which is ideal for a wide range of power management applications. Its low-dropout regulator and slew rate control feature, combined with its wide input voltage range, make it an ideal choice for projects which require a wide range of power sources and current capabilities.
