PMIC - Voltage Regulators - Special Purpose
The TPS65631DPDR is a dual-channel, high-accuracy, low-power, and low-dropout (LDO) linear voltage regulator. It features an input voltage range of up to 6V, with an output voltage range of up to 1.23V. The device has a typical accuracy of ±0.5% and a typical dropout voltage of just 100mV. It also has a shutdown function and provides a low 90µA quiescent current. The device has a very high power supply rejection ratio (PSRR) of up to 73dB at 10kHz, providing a very clean output voltage. This makes it ideal for powering active RF and data acquisition systems.
Application Field
Due to its very high accuracy and low dropout voltage, the TPS65631DPDR is suitable for many application fields, such as: Computer peripheral devices, Active RF systems, Portable medical equipment and Data Acquisition Systems.
Working Principle
The device takes an input voltage, typically from a battery or other DC power source, and using a series of voltage dividers, reference voltage and other components, outputs an accurately regulated voltage at the output terminal. The device has two independent output channels, which allows for the power supply of two subsystems with a single device. The device is made up of two stages, the error amplifier and the output stage. The error amplifier provides the necessary current to the output stage, while the output stage contains the circuitry necessary to provide a stable voltage to the load.
The error amplifier compares the output of the device to an internal reference voltage and regulates the output voltage accordingly. The output voltage is further regulated by a series of transistors, resistors and voltage dividers. When the output voltage deviates from the target voltage, the error amplifier sends a signal to the output stage, which then adjusts the voltage at the output terminal. This process continues until the output voltage reaches the desired level.
Conclusion
The TPS65631DPDR is a dual-channel, low-noise, low-power and low-dropout voltage regulator. It features a very high accuracy of ±0.5% and a very low dropout voltage of just 100mV. The device also has a very high PSRR of up to 73dB at 10kHz. This makes it ideal for powering active RF and data acquisition systems. The device is suitable for many application fields, such as Computer peripheral devices, Active RF systems, Portable medical equipment and Data Acquisition Systems.
