S-1313B2J-A4T1U3

PMIC (Power Management Integrated Circuits) are system elements that play a vital role in modern electronics. They manage the power distribution of most electronic systems, including personal computers, mobile phones, and other embedded systems. PMICs are often based on different architectures and have to fulfill many functions, such as monitoring and regulating input voltage, regulating output voltage, controlling fan speed and load current, etc.One of the most popular architectures used in PMICs today are Linear Voltage Regulators (LVRs). These types of system components provide the necessary stable voltage for efficient power supply for the integrated circuits in a system or device. In an LVR, the output voltage is varied depending upon the input voltage and the settings of the voltage regulator. The output voltage is adjusted through an internal feedback mechanism to maintain a constant output voltage. The current passing through the LVR is also regulated, ensuring that no overload or short circuits occurs within the system.The S-1313B2J-A4T1U3 is a Linear Voltage Regulator (LVR) from TDK-Micronas, widely used in various applications. It is a low noise, small size and high accuracy LVR with adjustable output. The operating temperature range of this LVR is -40 °C to 125 °C, while its standby current consumption is only 5 µA, making it one of the most efficient LVR’s available in the market. The maximum output error of this system component is 0.5%, which makes it one of the most accurate LVR’s available. This LVR is able to discover quickly whether an under-voltage or an over-voltage situation is present and act accordingly, providing an efficient and reliable power regulation. The S-1313B2J-A4T1U3 finds its application in various electrical and electronic devices, such as PDUs, distributed power systems, automotive power systems, solar power systems, motor drives and automation systems. Its adjustable output voltage range from 2.8 V to the maximum voltage you set and its output current of 1.5 A at 25 °C makes it ideal for a wide range of applications.The S-1313B2J-A4T1U3 works usually as an input voltage regulator, where the output voltage is adjusted continuously to the fixed output voltage level, depending on the input voltage value. This is accomplished by feeding a portion of the output voltage back to the noninverting input of the internal comparator. When the output voltage changes, the voltage at the noninverting terminal will change accordingly. When the voltage at the noninverting input rises above a certain level, the output of the internal comparator will turn off, turning the transistor off, thus stopping the flow of current to ground. The output of the S-1313B2J-A4T1U3 is regulated according to the internal voltage reference, which is set by the two external components R1 and R2. The internal reference voltage is determined by the resistor network formed by R1 and R2. The output voltage of this LVR is adjusted by sensing the output voltage and comparing it with the internal reference voltage. If the output voltage rises above the reference voltage, the internal transistor will be turned off, thus reducing the output voltage. If the output voltage falls below the reference voltage, the internal transistor will be turned on, thus increasing the output voltage.As can be seen, the S-1313B2J-A4T1U3 is a reliable, small and efficient Linear Voltage Regulator (LVR). This system component can be used in a wide range of applications and provides an accurate, stable and efficient voltage regulation.
