REG104FA-5/500 is a linear voltage regulator from Power Management Integrated Circuit (PMIC) and is widely used in electronics circuit design. It is a three-terminal adjustable fixed-output regulator and its output range is adjustable from 2.5V to 27V. REG104FA-5/500 is stable, reliable, and widely used in a wide range of applications, such as regulated power supplies, linear regulators, and general-purpose power-supply designs.

REG104FA-5/500 features a low current offset of 10 to 15mV, a voltage drop of 2.5V, and a low quiescent current of 10µA. In addition, the maximum input voltage is 40V and the minimum input voltage is 8V. It also provides an output current limit of 500mA and its operating temperature range is -40°C to +125°C.

REG104FA-5/500 is a common application for low noise, low ripple, and low power supply designs. It is suitable for applications in automotive and industrial control systems, HVAC systems, LED drivers, electronic instrumentation, and consumer products. It can also be used in power supply circuits for medium or high currents, audio video equipment, and communication systems.

The working principle of REG104FA-5/500 is similar to that of other linear voltage regulators. It consists of an operational amplifier (op amp), an Darlington transistor, and a voltage divider. When the Vin is applied to the input and regulated voltage is obtained at the output, the operation of the op amp directs the current flow through the Darlington transistor to control the output voltage. The voltage divider is used to generate the reference voltage which is compared with the input voltage. If the input voltage and reference voltage differ, then the current flow is adjusted to maintain a constant output voltage. By controlling the current flow from the input side, the output voltage is regulated.

REG104FA-5/500 is a highly efficient voltage regulator that is used to produce a constant and stable output voltage. It is widely used in various electronic circuits and applications because of its high efficiency, stability, and reliability. Its low quiescent current, current offset, and voltage drop make it an ideal choice for high-power applications. Its low noise and low ripple make it a popular choice for low power supply applications. It is also used in various voltage regulators and linear regulators that require a continuous and reliable input voltage.
