REG104FA-2.5/500

PMIC - Voltage Regulators - Linear

REG104FA-2.5/500 are linear voltage regulators capable of sourcing up to 500mA of current. The device is available in a variety of packages that make it suitable for a wide range of applications.

Application Field

REG104FA-2.5/500 is designed to be used in any application that demands high stability and precision, especially in embedded systems. It is widely used for DC/DC converters, power management, portable embedded systems, industrial and consumer electronic devices.

Working Principle

REG104FA-2.5/500 operates in three distinct modes: active, calibration, and low-power. The active mode is the most commonly used mode, and the device will remain in this mode unless otherwise instructed. In this mode, the device uses two internal Schottky diodes and two internal PNP transistors as its power supply inputs, and the current regulation is also set in this mode.

The calibration mode is used to ensure proper operation of the device. In this mode, the device is disabled, and the offset of the reference voltage is trimmed to achieve improved accuracy.

The low-power mode is used to reduce power consumption when the device is not in active use. In this mode, the output current is reduced to a minimum of 1µA.

As for the device protection features, the device features thermal shutdown, overvoltage protection, overcurrent protection, short circuit protection, and current limit protection.

Conclusion

REG104FA-2.5/500 is a linear voltage regulator capable of offering stable operation in a wide range of applications. It operates in three distinct modes and provides a number of protection features. The device is available in a variety of packages, making it suitable for a wide range of embedded systems.
