The LP5900TLX-2.1/NOPB is a high-efficiency, low-dropout (LDO) linear voltage regulator designed for use as a power supply buffer used in applications such as cell phones. It is classified as a PMIC (power management IC) voltage regulator, offering a 3.2V to 5.5V adjustable output voltage range. The device features integrated ESD protection, thermal protection, and output voltage monitoring that can detect circuit voltage drop-out conditions and shutdown operation to prevent power failure.
Features
The LP5900TLX-2.1/NOPB has several features that make it an attractive option for power management applications. It includes a wide input voltage range of 2.3V to 5.5V, enabling it to be used in a variety of power supply buffer designs. Its high output current capability of up to 500mA combined with its 2.5Ω maximum on-resistance allows it to drive heavy load circuits. Its low quiescent current of only 7μA and standby current of 0.33μA conserve battery power and optimize efficiency. For added protection against short circuits and over-temperature conditions, the device includes various protection features such as thermal shutdown, short circuit protection, output over-voltage protection, and under-voltage lockout.Application Field and Working Principle
The LP5900TLX-2.1/NOPB is designed for use as a power supply buffer in portable applications such as cell phones, PDAs, digital cameras, and other devices that need to maintain a stable power supply. The device works by regulating the output voltage to a predetermined level. It does this using an internal error amplifier that senses the output voltage and compares it with a reference voltage. If the output voltage goes above or below a certain threshold, the error amplifier sends a signal to the output control circuit. The output control circuit then adjusts the output voltage to bring it back to the reference voltage.When the device is in shutdown mode, it will reduce its quiescent current to approximately 19μA. This low quiescent current further enhances the power savings of the device.Conclusion
The LP5900TLX-2.1/NOPB, with its high efficiency, low drop-out voltage and low standby current, is an ideal device for use as a power supply buffer in portable applications such as cell phones. Its wide input voltage range, high output current capability, and integrated protection features make it an attractive and reliable choice for power management applications.The specific data is subject to PDF, and the above content is for reference
