The REG71050DRVRG4 is a PMIC Voltage Regulator DC DC Switching Regulator, that is employed in delivering regulated supply voltages when connecting with the microprocessor directly or indirectly. It offers the capability to maintain required voltage levels to the microprocessor, as well as improved adjustment range without the need for valuable external components.

The REG71050DRVRG4 is a switch-mode DC/DC step-down regulator. It provides fixed regulated output voltages of 0.75V/1.2V/1.5V/1.8V/2.5V/3.3V/5.0V/6.0V and adjustable output voltage. It provides a high efficiency switch-mode buck regulator, with a load current up to 1A and a switching frequency that can be set between 200kHz to 1.5MHz, depending on the application.

The REG71050DRVRG4 features a low maximum input voltage of 7.5V, a low quiescent current of 3uA and integrated over-temperature protection. It also has an external synchronous rectification option, which allows for higher efficiency and improves thermal performance.

The REG71050DRVRG4 is a low quiescent current, high efficiency 3V to 60V buck switching regulator. It has a wide operating temperature range that allows it to be used in automotive, industrial, consumer and medical applications. This makes it a great choice for applications requiring precision voltage regulation for microprocessors and embedded logic circuits, as well as for other sensitive components.

REG71050DRVRG4 is an integrated low-voltage step-down regulator, with an internal power switch, that offers excellent load and line transient response, integrated high frequency oscillator and soft start. It also features adjustable current limit and over-temperature protection, adjustable power switch currents and short circuit protection.

The working principle of the REG71050DRVRG4 is that it acts as a switch-mode voltage regulator, where a voltage reference and error amplifier control the duty cycle of a high speed switching element in order to regulate the output voltage. The error amplifier compares the output voltage with the reference and adjusts the duty cycle to keep the output voltage at the reference voltage level. As the switching element switches at high frequency, it generates a waveform with a peak-to-peak voltage that is much higher than the output voltage, which is then stepped down using an output inductor and output capacitors.

REG71050DRVRG4 is an ideal regulator for powering the microprocessors and other sensitive devices, as it is a low quiescent current, high efficiency DC to DC buck switching regulator with wide operating temperature range and adjustable power switch current limits. It is also a great choice for low-power devices, like mobile phones and tablets, and battery-powered applications that require a precise voltage regulation.
