SC2453ITSTRT is a versatile voltage and current regulator designed for a wide range of applications across the industrial, commercial and consumer sectors. This PMIC Voltage Regulator can be used to precisely control the output voltage and current of alternating current (AC) and direct current (DC) sources, with a range of features such as line, load and temperature compensation. In addition, the regulator has built-in protection against short circuit, over current and over voltage conditions, making it ideal for powering sensitive and complex systems.

SC2453ITSTRT is classified as a linear and switching regulator, delivering extended accuracy and efficiency for a variety of power management applications, including powering regulated systems in automotive, industrial, computer and consumer product applications. It also functions as a universal voltage regulator for low-voltage and high-voltage, low-current and high-current systems.

Linear and Switching Regulator Design

SC2453ITSTRT is a linear and switching regulator featuring low-dropout (LDO) technology. The LDO design allows this PMIC Voltage Regulator to provide a precise output voltage, irrespective of changes in input voltage and line regulation. Furthermore, the regulator’s low-noise, ultra-low-noise, and low-ESR capabilities make it ideal for powering sensitive, high-precision systems.

SC2453ITSTRT is designed to allow the user to select either linear or switching operation. PWM-type or pulse-width modulation-type switching operation provides a fast response and high efficiency. Linear operation has the advantage of providing very low output noise, excellent line-load regulation, and long-term voltage stability.

Typical Applications

SC2453ITSTRT offers robust and reliable power management for systems that require input voltages from 3V to 30V. This PMIC Voltage Regulator can also be used in a wide range of applications across the consumer, commercial and industrial sectors, including:

• Computers and consumer electronic products, such as computers, mobile devices, and gaming systems;
• Industrial and automotive applications, such as motorcycles and construction vehicles;
• Telecommunication devices, such as cell phones and radios;
• General AC and DC power sources.

Working Principle

At the heart of SC2453ITSTRT is a highly efficient and reliable voltage regulator that uses a set of semiconductors (such as MOSFETs) to control the voltage and current output of the regulator. The semiconductors work in cooperation with other components to regulate the current and voltage output of the regulator. To ensure precise and consistent output, the regulator incorporates a feedback loop.

The regulator takes an input voltage and current, measures it, and adjusts the output voltage and current accordingly. When the input voltage and current are within the specified range, the regulator will maintain a steady output voltage and current. If the input current or voltage exceeds the specified range, the regulator will adjust the output voltage and current accordingly. If a short circuit or over current condition occurs, the regulator is designed to shut down to protect the system.

With the regulator’s integrated line, load and over temperature compensation, it is able to maintain a precise output voltage and current, irrespective of changing conditions. This makes it ideal for powering a wide range of systems in the industrial, commercial and consumer sectors.
