LP2988IM-5.0 is a low-dropout, two-terminal regulator with a fixed 5.0V output voltage. It provides a maximum load current of 500mA, and a maximum junction temperature of 125℃. It is suitable for a variety of different applications, and its working principle is based on the regulation of controlled current and voltage.
Application Fields
The LP2988IM-5.0 is typically used in a wide range of applications, including cellular phones, PDAs, hand-held computing devices, digital cameras, digital camcorders and other portable consumer electronics. It is also used in industrial systems and automotive systems, such as adjustable power supply systems for industrial process controls, automobile battery monitor and fuel injection systems, UPS systems and motor control modules.Features
The LP2988IM-5.0 has several features that make it ideal for use in many applications:- Low-dropout, two-terminal regulator with a fixed 5.0V output voltage.
- Maximum load current of 500mA.
- Maximum junction temperature of 125℃.
- Thermal shutdown and short-circuit protection.
- High accuracy output voltage regulation.
- High AC and DC ripple rejection.
- Low ground current.
- Low output voltage noise.
- Low EMI susceptibility.
- Wide input voltage range.
Working Principle
The LP2988IM-5.0 is a low-dropout regulator, which means that it can regulate the output voltage even with a very small input-output differential. The regulator utilizes current regulation for improved transient response and enhanced regulation accuracy. The voltage across the regulator is maintained at a constant level by controlling the output current.The regulator works by sensing the output voltage and comparing it to an internal, stable reference voltage. The controller then adjusts the voltage, based on this comparison. If the output voltage decreases, the controller increases the current and vice-versa. This regulation process is done mainly via two transistors and a power transistor, which are internal to the regulator.The LP2988IM-5.0 is protected by several safety features, including overtemperature and short-circuit protection. In the case of overtemperature, the regulator automatically shuts down and the output voltage will fall to 0V. In the case of short-circuit protection, the regulator will automatically reduce the output current.Conclusion
The LP2988IM-5.0 is a low-dropout, two-terminal regulator with a fixed 5.0V output voltage. It is designed for a variety of applications, such as cellular phones and automobile systems. It has several features, such as low-dropout, thermal shutdown and short-circuit protection, to ensure optimal operation. The regulator utilizes current regulation for improved transient response and high accuracy output voltage regulation. With these features and its wide input voltage range, the LP2988IM-5.0 is an ideal linear regulator for many applications.The specific data is subject to PDF, and the above content is for reference
