REG711EA-2.7/2K5G4

The REG711EA-2.7/2K5G4 is a monolithic switching regulator designed to provide a regulated output voltage with a low dropout voltage, while operating from wide range of input voltages. This device can be used in cost sensitive, low power applications, such as battery-powered systems. It is typically used in LED drivers, power supplies, and power converters, and many other electronic applications.

DC DC Switching Regulators

DC-DC switching regulators are power conversion systems that take an input voltage, typically from a battery, and convert it to an output voltage level that is suitable for an end device. Switching regulators are a type of power-supply circuit that converts a DC input voltage to a DC output voltage. This is done using a switching device such as a transistor to turn the circuit on and off and to regulate the output voltage.

Switch mode power supplies are classified into two main types: DC-to-DC and AC-to-DC converters. DC-to-DC switching converters are used to convert a DC input voltage to a different DC output voltage, while AC-to-DC converters are used to convert an AC input voltage to a DC output voltage. Switch mode power supplies may also be classified by topology, such as buck, boost, buck-boost, or flyback.
