The LP38852SX-ADJ is a dual Low Dropout (LDO) linear voltage regulator. It is a power management integrated circuit (PMIC) with low dropout performance and programmable output voltage. The device provides users with the ability to independently adjust the voltage levels of two supplies from 1.2V to 3.6V. It can provide a maximum output current of 1.1A and a load regulation of 0.2%. This makes the LP38852SX-ADJ perfect for applications that require a wide range of voltage levels.

The LP38852SX-ADJ PMIC utilizes an advanced CMOS process for high efficiency and low noise. It is an adjustable regulator with no external reference voltage needed and no external compensation. It has a high accuracy voltage regulation with low dropout voltage of only 0.3V. Its wide input voltage range of 2.5V to 5.5V make it applicable to many applications. The output pin of the device is functional in shutdown mode and the load is disconnect from the output when the device is in shutdown.

The LP38852SX-ADJ is designed for a variety of applications including battery-powered systems with dual supply requirements, parallel rail requirements, point-of-load (PoL) regulation, and general circuit power applications. Its wide input voltage range make it ideal for low voltage and high voltage applications. Its low noise output and adjustable output voltage make it suitable for power control in audio applications, industrial designs, and communication infrastructure.

The working principle of the LP38852SX-ADJ PMIC is as follows. It converts a DC input voltage (Vin) to a regulated output voltage (Vout) via an internal error amplifier, voltage reference, current source, and other logic and control circuits. The voltage regulation is achieved by controlling the output current. The current source is regulated through a feedback voltage loop comprising of the error amplifier, voltage reference, and the current source. The error amplifier compares the output voltage to the reference voltage, which is an adjustable source, and adjusts the current source to maintain the output voltage at its setpoint. The output voltage can be adjusted by changing the reference voltage.

The LP38852SX-ADJ is a solution for both high voltage and low voltage applications, as it has an adjustable output voltage from 1.2V to 3.6V as well as a wide input voltage range of 2.5V to 5.5V. Its low dropout voltage of 0.3V, high accuracy voltage regulation and low noise output make it suitable for a variety of applications such as audio, industrial and communication infrastructure. Furthermore, its ability to be shut down without any external components makes it easier to implement, saving resources and time.
