The LP38692SD-2.5 is available in both a 10-lead TSSOP and an 8-lead MSOP package. Working Principle
The LP38692SD-2.5 is a low-dropout linear voltage regulator, and it operates on a simple principle. It is essentially a resistor that is connected to a power source and that is used to drop the voltage of the power source. The LP38692SD-2.5 employs a Pierce-style insulated gate bipolar transistor (MOSFET) as part of its design and this allows for a rapid response time, controlled by the device\'s control loop. When the input voltage of the LP38692SD-2.5 is greater than its reference voltage, the control loop makes sure that it stays in regulation by controlling the gate voltage in the MOSFET. The MOSFET is then used to drop the input voltage, so that the regulation is maintained. The output of the device is therefore regulated and is able to supply a fixed voltage. The LP38692SD-2.5 also has thermal protection which prevents the device from operating in a situation where the temperature exceeds the upper temperature limit. This is done by using an on-chip thermal shutdown circuitry, which monitors the temperature of the device and shuts it off if it exceeds the specified limit. This prevents the device from damage due to over-temperature or thermal runaway.Summary
The LP38692SD-2.5 is a highly versatile low-dropout linear voltage regulator that is suitable for a wide range of applications. It is categorized in the power management integrated circuit (PMIC) and is a member of the voltage regulator group specifically belonging to the linear regulator category. The LP38692SD-2.5 offers a wide range of features such as low dropout voltage, tight output voltage accuracy, short circuit protection, over current protection, thermal shutdown protection and current limiting. It also offers a fast line and load transient response. The LP38692SD-2.5 is highly reliable and its working principle is based on the use of a MOSFET in a Pierce-style design, which makes it an ideal device for many applications.
