Introduction

The REG104FA-3.3/500 is a high-performance precision voltage regulator, which has been specifically designed to provide a stable 3.3 V output with an output current up to 500 mA. It is a monolithic, single-channel, low drop-out (LDO) linear regulator, with a low input/output voltage differential and excellent output stability. This device is capable of regulating output currents up to a maximum of 500 mA.The REG104FA-3.3/500 is a tool of choice for many applications, including cellular phone power, point-of-use regulators, and DC/DC converters.

Application Field

The REG104FA-3.3/500 is ideal for a wide range of applications. Its high efficiency, very low noise and large current capability makes it perfect for powering low voltage digital ICs. It can also be used for small power supplies, personal electronics, portable systems, battery-powered devices, industrial control systems, automotive electronics, personal computers, and more.It is well suited for point of use (PoU) voltage regulators, cellular phone power management, automobile electronics, automotive communications and process control. It has an excellent power supply rejection ratio and low input/output voltage differential that enables a very low dropout voltage, resulting in efficient regulation at light loads.In addition, the REG104FA-3.3/500 can be used in conjunction with a switching regulator or DC/DC converter. This allows the device to be used at a high-efficiency level, while maintaining excellent output performance.

Working Principle

The REG104FA-3.3/500 is a linear-regulator type Voltage Regulator. It uses two metal-oxide semiconductor field-effect transistors (MOSFETs) to operate in a linear mode.When in operation, the device monitors the input current, and is responsible for regulating the output voltage to the desired level. The voltage output is regulated by an internal voltage reference, which is typically 0.45 V. When the input voltage is higher than the output voltage, the MOSFETs supply current to the load. If the input voltage is lower than the output voltage, then the MOSFETs will be turned off, thus preventing any current from flowing to the load.In normal operations, the current being supplied to the load is determined by the difference between the inputs voltage and the output voltage, as well as by the current output capability of the device. The REG104FA-3.3/500 also features a built-in over-current and thermal protection, which prevents the device from being damaged in case of over current or thermal overload.

Conclusion

The REG104FA-3.3/500 is an excellent choice for any application that requires a precision voltage regulator. It is highly efficient and has an excellent power supply rejection ratio, allowing it to accurately regulate even at light loads. It also features an excellent thermal protection and over-current protection that prevents the device from being damaged in case of an emergency. In addition, it can be used in conjunction with a DC/DC converter or switching regulator, allowing it to operate at a high-efficiency level while still providing excellent output performance.
