The LP38501TJ-ADJ/NOPB is a linear voltage regulator that belongs to the PMIC (Power Management IC) family of products. It offers an adjustable output voltage (5V to 20V) with a maximum load current of 25mA. The device is designed to deliver high performance while occupying minimal board space, making it an ideal choice for applications where space is a limiting factor.The LP38501TJ-ADJ/NOPB uses a two-stage approach consisting of two linear connected stages. The first stage is a series linear transistor acting as a shunt regulator. The second stage is a low-power buck-boost regulator, which adds flexibility to the output voltage by adjusting the current drawn from the shunt regulator. This enables the device to provide output voltages over a range of 5V to 20V to suit the application requirements.The shunt regulator consists of a voltage adjusting device, coupled with a series pass transistor which allows the current to flow from the power source to the load. The output of the shunt regulator is fed to the buck-boost regulator stage, which adjusts the current by varying its output voltage. The buck-boost regulator can support output voltages ranging from 5V to 20V and is capable of providing output currents of up to 25mA.The LP38501TJ-ADJ/NOPB has several features that make it suitable for use in a wide range of applications. The device is capable of operating within an extended temperature range of -40 to 125°C and comes equipped with over-temperature protection and output short circuit protection to ensure the device performs reliably in harsh environments. The device is also RoHS compliant, which makes it an ideal choice for green projects.The LP38501TJ-ADJ/NOPB is an ideal choice for a variety of applications, such as UPSs, automotive and automotive derivative circuitry, and other voltage regulation and power management tasks. Its small size and high performance make it an ideal choice for managing power consumption in space-constrained applications. It offers the flexibility to adjust the output voltage over a wide range, making it suitable for a wide variety of applications.
