S-1112B49PI-L7ITFU Application Field and Working Principle

The S-1112B49PI-L7ITFU voltage regulator is a linear voltage regulator in the Power Management Integrated Circuit (PMIC) product family. This device is a low power, low dropout (LDO) voltage regulator, which is capable of outputting a constant voltage across a wide range of input voltages. The device is specified for an output voltage of 5V and can handle an input operating voltage range of 1.5 to 6.5V.The S-1112B49PI-L7ITFU regulator is designed to provide a stable output voltage with low power consumption in a variety of portable device applications. It is ideal for applications that require low voltage, low quiescent current, and low noise operation of power management systems. It is ideal for applications such as cellular phones, Medical Electronic Equipment, Battery Supplied Systems, and Automotive Applications.The S-1112B49PI-L7ITFU regulator is part of a larger family of low voltage dropout voltage regulators (LDOs) offered by Semisoft. It is designed to provide excellent load regulation and ripple rejection in a compact package. This LDO can be used in various applications with its high output current capability and low dropout. It is well suited for battery powered equipment, which requires low input and can tolerate low output voltages. It can also be used in cases where ripple rejection is critical and noise sensitive applications.The S-1112B49PI-L7ITFU voltage regulator operates on the principle of a voltage ref axed current source. Its two main components are a current mirror and a pass transistor. The current mirror is essential for the devices electrical stability and tracks the output current and keeps the voltage at a very precise level regardless of the load. The specifically designed pass transistor establishes an output voltage that is almost equal to the regulator’s reference voltage.The S-1112B49PI-L7ITFU regulator is also equipped with a selectable soft start feature that can set a time reference for specified time constant to limit its input current when the system is powered up. The device also includes an internal ultra-low power high accuracy voltage reference, a voltage error amplifier, a frequency compensation network, a logic level P-channel MOSFET, and a thermal shutdown feature.The S-1112B49PI-L7ITFU is available in a space saving SOT-223 package. It is designed to operate over a wide input voltage range and provides over-temperature protection with thermal shutdown. It also has a reverse current protection and a shut down function. The device also features a low drop out voltage, a low input current, and low noise operation.The S-1112B49PI-L7ITFU voltage regulator is an excellent choice for those looking for an efficient means of regulating voltage in low power systems. Its low dropout voltage and low input current make it ideal for these applications. Also its wide operating temperature range and robust thermal protection make it suitable for a wide range of temperature operating conditions. Its small size and wide input voltage range make it easy to integrate into a variety of systems. This product is highly recommended for applications that require precise output regulation at a low cost.
