TPS77801DG4

TPS77801DG4 is a low-power positive voltage regulator with 1.5A output current. It features an input voltage range of 2.2V to 10V, enabling a wide range of power solutions. It can be used for a variety of applications, including Li-ion battery powered products, automotive, industrial and handheld portable systems.

The TPS77801DG4 is a two-terminal linear voltage regulator IC. It consists of two voltage reference, one active element and a throttling and protection circuit. Instead of just supplying the output voltage, the device is able to automatically adjust the output voltage according to varying input and load conditions, thus offering better energy efficiency.

The device operates in two modes: regulation and standby. In regulation mode, the reference voltage, Vref, is set to the output voltage desired. The active element is a differential amplifier with the error amplifier comparing the output voltage to the reference voltage and adjusting the output voltage by controlling the time element. The time element is a High Low optimized transistor array, which is adjusted by the error amplifier in order to accurately and quickly output the desired voltage. In Standby mode, the Vref is set very low, then the active elements are turned off, thereby significantly reducing power consumption.

The key features of the TPS77801DG4 include input voltage range of 2.2V to 10V, output voltage range of 0.8V to 10V, low output voltage ripple and low power dissipation. The device also incorporates short circuit, over-temperature, current limiting and thermal protection.

The TPS77801DG4 is suitable for a variety of industrial and consumer applications such as portable and battery powered products, automotive, industrial and handheld portable systems. The device can be used in a wide range of applications such as low noise and high temperature applications, low noise and automotive applications, and portable medical and consumer applications.

In conclusion, the TPS77801DG4 is a two-terminal linear voltage regulator IC with a wide input voltage range of 2.2V to 10V and an output voltage range from 0.8V to 10V. It features a low output voltage ripple and low power consumption, and incorporates safety features such as short circuit, over-temperature, current limiting and thermal protection. The device is suitable for a variety of industrial and consumer applications.
