LP38858SX-0.8 is a three-terminal adjustable low dropout (LDO) linear voltage regulator that features an extremely low dropout voltage of 0.75V at 1.5A of load current. The device is designed to provide low noise and high PSRR, making it ideal for portable applications such as notebook computers and cell phones.Its integrated P-channel MOSFET and integrated current limit circuit helps to reduce total system cost while its high accuracy, low temperature coefficient and low ground current ensures that the LP38858SX-0.8 meets the most demanding applications.The LP38858SX-0.8 is suitable for use in multiple markets, spanning a wide range of portable, battery powered applications such as mobile phones, PDAs, MP3 players and digital cameras. It can also be used in custom embedded systems; where its adjustable output helps provide a flexible power delivery solution.ApplicationsThe LP38858SX-0.8 is well-suited for multiple applications and can be used in applications such as:Portable and battery-powered devices: Mobile phones, PDAs, MP3 players, digital cameras and custom embedded systems.Computers and peripherals: Motherboards / Notebooks, Desktops and clusters, Servers, and embedded applications and set-top boxes.High voltage applications: Tape recorders, CD and DVD players, car audio equipment, and display units.Medical equipment: Personal care devices, medical imaging and monitoring, and medical test and measurement.Industrial applications: Robotics, process control and instrumentation, and aerospace and defence.Working PrincipleThe LP38858SX-0.8 is based on a two-stage topology that consists of an input bias circuit and an internally compensated voltage regulator. The input bias circuit is responsible for controlling the quiescent current of the device and providing an adjustable output voltage. The regulator stage controls the output voltage and limiting the amount of released output current.The input bias circuit contains three external components — two resistors and a capacitor — which are used to set the desired output voltage. The internal devices limit the output current by sensing the voltage drop across the output and re-setting the bias circuit to prevent the output voltage from going too far out of regulation.The output current is set by the location of the sense resistors on the input/output rail. When the current limit is reached, the resistor’s voltage increases, deceasing the input to the gate of the main voltage regulator. This reduces the output voltage, limiting the amount of current flowing through the device.The LP38858SX-0.8 is designed to be extremely easy to use, with all the necessary inputs and outputs on a single footprint. The device’s adjustable output allows it to be used in a wide variety of applications. It also has excellent noise and PSRR specifications, providing a reliable solution for noise-sensitive applications.The LP38858SX-0.8 provides a cost-effective solution to a wide range of applications and is available in a small SSOP-8 package. It’s the ideal choice for any application requiring low noise, superior PSRR, and a low dropout voltage.
