Introduction

EY1602SI-ADJ is a low-current low-dropout positive adjustable regulator from EPOS Corporation electronics. This type of linear regulator is typically used in power management applications such as CPU and computer power, audio and video applications, and any other application requiring precise regulation of an output voltage.  This particular regulator  is designed to be extremely robust and delivers a maximum current of 0.95 A, accommodating a wide input voltage range of 2.5 V to 38 V.

Application Field

The EY1602SI-ADJ is a versatile device and can be used in various applications that require precise voltage regulation; some applications include:

• Computers and servers power supplies
• Computer periperals, such as displays and printers
• Audio and video applications
• High-current LED lighting systems
• Automotive applications

The EY1602SI-ADJ is also suitable for applications where large output currents are required. This is one of the few linear regulators that can deliver up to 0.95 A of output current in a very compact package, due to it\'s exceptional thermal design and robustness.

Working Principle

The working principle of the EY1602SI-ADJ is quite simple - it is a linear regulator that works by reducing the input voltage to the level required by the device. This is achieved by the embedded voltage feedback loop and the internal pass transistor that act as a current sink when the voltage at the output node crosses the desired regulation level.

When the output voltage is lower than the desired level, the internal pass transistor acts as a current source, and it increases the voltage at the output node. To ensure a precise regulation of the output voltage, the voltage feedback loop monitors the output voltage level and adjusts the current state of the internal pass transistor, thus adjusting the output voltage.

It is important to note that the load current of the EY1602SI-ADJ is limited by the maximum current (0.95 A) of the device. This means that the available output current is proportional to the input voltage. Therefore, it is recommended, for high current applications, to use a higher input voltage.

Conclusion

The EY1602SI-ADJ is a versatile linear regulator that can be used in various applications due to its wide input voltage range and maximum current of 0.95 A. Its simple working principle and robust design provide a precise and reliable regulation of the output voltage, making it a great choice for all kinds of power management applications.
