Evaluation Boards - Linear Voltage Regulators

Linear voltage regulators are used when a system requires consistently reliable voltage regulation. One of these linear voltage regulators is the LP38693-ADJEV, which is designed to deliver up to 800mA of continuous output current. This powerful voltage regulator enables designers to build systems where the desired voltage and load current requirements can be accurately adjusted and maintained with an adjustable output voltage, up to 4.6V.

The LP38693-ADJEV has a wide input voltage range, between 1V and 4.6V, making it suitable for use in a variety of design environments. Its output is suitable for a variety of applications, with adjustable output voltage from 0.8V to 4.6V and externally adjustable current limit from 35mA to 800mA. This voltage regulator has low shutdown current draw and low quiescent current draw, which keeps battery life high.

The LP38693-ADJEV is specifically designed as a low-noise choice for a variety of tasks and applications. Its 180mV dropout voltage at 800mA load and low quiescent current demands make it an ideal choice for precision applications, such as portable medical devices or sensitive audio applications. As it also offers excellent power supply rejection, ripple rejection, and thermal performance, the LP38693-ADJEV is a great option for any application needing reliable voltage regulation in noisy environments.

The LP38693-ADJEV uses a simple two-stage voltage regulating design, consisting of an internal error amplifier, a comparator, and a driver. The voltage reference is regulated by the error amplifier. This voltage then passes to the comparator which compares it to the external reference voltage. Then, the driver provides output voltage based on the error amplifier’s output voltage and the comparator’s output voltage.

The LP38693-ADJEV contains several safety features, such as an overtemperature protection circuit that shuts the device down when the die temperature exceeds a certain threshold, and a current-limiting circuit which as mentioned provides adjustable current limit from 35mA to 800mA. This minimizes the chance of overload or short circuit damaging the device.

The LP38693-ADJEV is a highly versatile linear voltage regulator with a wide input voltage range and adjustable output voltage. It provides excellent power supply and ripple rejection, low noise operation, and low quiescent current draw, making the LP38693-ADJEV an ideal choice for a variety of applications, including portable medical and audio devices, and any application that requires reliable voltage regulation in a noisy environment.
