The LP38852MRX-ADJ/NOPB is a high performance, fixed output voltage, low drop-out (LDO) linear regulator that is designed to meet the stringent requirements of today’s highly advanced, high-power mobile device applications such as smartphones, mobile phones, tablets, and other portable devices. The device offers very low quiescent current, low drop-out voltage, high load current capability, and ultra-low noise performance. This device is designed to provide a regulated voltage output up to 3A. It is capable of providing tight load regulation even when operating in an environment of large input voltage variations.

The LP38852MRX-ADJ/NOPB is a two-terminal adjustable regulator with an integrated internal trim resistance network. The voltage reference is designed to be directly adjustable from 0.8V to 3.3V, with a minimum step size of 0.2V. It provides excellent line and load regulation performance (less than 0.2% typical over temperature and line) with a low quiescent current of only 0.3 mA. Its ultra-low noise profile (typically 1.8 μVP-P at 3.3V, 5 mA) makes it ideal for powering audio circuits.

The LP38852MRX-ADJ/NOPB works by comparing the input voltage to an internal reference voltage and regulating the output voltage so that it remains constant. When the input voltage is greater than the reference voltage, the output voltage is pulled lower with a corresponding increase in current until the input and output voltages are equal. The LP38852MRX-ADJ/NOPB features a fast-response power-regulated loop, providing low transient response time.

The device is highly efficient, with a maximum efficiency of 96%. It is also protected against short circuits and over-temperature operation, which helps to ensure long-term device reliability. The LP38852MRX-ADJ/NOPB is offered in the industry standard 4x5mm QFN package and is available in multiple configurations, providing flexibility and performance for a wide range of applications.

In conclusion, the LP38852MRX-ADJ/NOPB is an ideal choice for high-end mobile device applications, such as smartphones, mobile phones, tablets, and other portable devices, offering low drop-out voltage, high load current capability, ultra-low noise performance, and high efficiency. It is capable of providing tight load regulation even when operating in an environment of large input voltage variations. The device offers very fast transient response and is offered in multiple configurations for flexibility and performance.
