PMIC, or Power Management Integrated Circuit, is one of the most commonly used electrical component that provides a wide range of power supply and management functions for modern electronic equipment, including voltage regulation and current limiting. In this article, we will focus on linear voltage regulators, more specifically, the RT9073N-18GB, which is a three-terminal adjustable negative linear voltage regulator.
The RT9073N-18GB is typically used in applications such as LDO voltage regulation, ultra-low noise and ripple, multi-stage stability, and fast transient response. Its features such as low dropout voltage, low current noise and low heat dissipation, making it an ideal solution for powering sensitive electronics in portable and desktop applications.
On the RT9073N-18GB, the three terminals are called input voltage (VIN), Ground (GND), and output voltage (VOUT). The voltage at the output can be adjusted, depending on the resistance applied to the adjustment terminal. Essentially, the regulator circuit functions as a variable resistor between the input and output, which allows the user to control the output voltage by changing the resistance setting.
The RT9073N-18GB employs a regulation loop, or feedback loop, to maintain its voltage output. When the output voltage reaches its value, the loop sends back a voltage to the regulator\'s control pin to reduce or increase the device\'s current consumption depending on the output voltage level. This feedback loop allows the regulator to adjust its current supply according to the load current requirement, and therefore maintain the output voltage regulation.
Aside from its adjustable output feature, the RT9073N-18GB also has a very low quiescent current—as low as 50uA—which makes it a great choice for applications that require low energy consumption. This low quiescent current also allows it to be used in battery-powered systems, extending the battery life.
The RT9073N-18GB also features high power line regulation and power supply rejection ratio, which ensures that the output voltage remains stable even when the supply voltage fluctuates. This makes the device ideal for use in fluctuating power supply environments.
The RT9073N-18GB also has a very low noise ripple and is thermal regulated, which provides excellent thermal stability and reliability in long-term operation. The device is also offered in a low-profile package, allowing it to be used in densely packed electronic systems without sacrificing performance.
To conclude, the RT9073N-18GB is a versatile three-terminal adjustable negative linear voltage regulator that is designed to provide low current noise and high line regulation in a wide range of applications. Its low dropout voltage, low quiescent current, and thermal regulation make it an ideal choice for battery powered and low-noise systems. It is also offered in a low-profile package, making it a suitable solution for tightly packed systems.
