The LP38690SD-Adj is a low noise, low dropout, 3-A linear regulator that combines low noise performance and load current capability. It includes a Low Dropout (LDO) voltage regulator, capable of supplying 3A of continuous load current, plus an adjustable output range of 1.230V to 5.5V. It is ideal for applications requiring low noise, low drop out, and low drift performance.

The LP38690SD-Adj is designed for single-cell Li-Ion battery-powered applications, such as thin-client systems, mobile computers, and digital audio players. The device offers excellent transient response, low noise operation, low dropout voltage, and load regulation. The low dropout voltage makes it an ideal choice for cost-sensitive applications that require high ripple rejection and minimal power loss.

The LP38690SD-Adj includes an advanced low output voltage design that allows it to easily support a 1.230V-5.5V output voltage range. It also includes an internal Voltage Reference (VREF) system which allows the voltage set-point to be adjusted dynamically to meet load current specifications. The adjustable feature offers excellent flexibility for any application, and the device comes with a wide variety of other features, such as over-temperature protection, thermal shutdown, and more.

The LP38690SD-Adj can be used in a wide range of applications, including microcontrollers, motion detectors, precision metering and instrumentation, power amplifiers/switches, CO/CO2 gas sensors, DSP-capable audio systems, and many more. It is an ideal choice for low power systems because of its high efficiency and low output noise. Its wide input voltage range of 2.7V to 5.5V, and output voltage range of 1.230V to 5.5V make it suitable for the wide range of devices and applications.

The LP38690SD-Adj offers the most advanced features and performance capabilities offering 3A of load current at a maximum output voltage of 5.5V with its low-noise, low-dropout, and low-power design. Its low-noise output performance eliminates the need for external filtering components, and its fast transient response makes it a perfect choice for powering microcontrollers. The adjustable voltage output feature allows a wide range of applications to be supported. The device also features over-temperature protection, thermal shutdown, and current limiting.

The working principle of the LP38690SD-Adj is very simple. It uses a PNP Bipolar Junction Transistor (BJT) to regulate the output voltage to the desired setting. The Bipolar Transistor senses the load current and adjusts its gate voltage to maintain the same desired output voltage set point. An external capacitor is used to maintain a stable output voltage independent of load current or supply voltage changes. The device works in linear mode, providing a well-regulated voltage output despite the wide input and load variations.

The LP38690SD-ADJ is the perfect solution for applications that require low noise, low drop out, and low drift performance. Its low output voltage range of 1.230V – 5.5V, adjustable output voltage range, fast transient response, and low power design make it an ideal device for low power applications. Its low noise and fast transient response allow it to be used without the use of external filtering components, making it an ideal device for cost-sensitive applications.
