LP38690DTX-2.5/NOPB is a linear voltage regulator that belongs to a family of power management integrated circuits (PMICs). It is designed to provide an adjustable output voltage between 2.5V to 4.5V, with an output current limit that is adjustable from 2A to 10A. The regulator is offered in an 8-pin NOPB package, which allows it to be easily mounted on most printed circuit boards (PCBs). It is suitable for a wide range of applications such as automotive, computing, telecommunications, industrial controls and consumer electronics.

The LP38690DTX-2.5/NOPB can be classified into two parts: the main regulator and the output stage. The main regulator includes a low noise low dropout (LDO) linear regulator and a comparator. The LDO linear regulator operates with a reference voltage set by the reference pin which is exact in relation to the output voltage. It can provide a minimum dropout of 60mV in full load conditions and a maximum of 80mV in full load conditions. The comparator monitors the voltage difference between the output voltage and the reference voltage. If the voltage difference exceeds 0.2%, the comparator raises an "over voltage protection (OVP)" warning.

The output stage is designed to convert the current provided by the main regulator into a stable output voltage, for applications that require higher currents. It consists of a pair of power MOSFETs arranged in parallel, a switching regulator and a current limiter. The power MOSFETs switch at a frequency of around 1.2 MHz, to provide an appropriate voltage output to the load. The switching regulator and the current limiter provide protection against overload, short circuit and overvoltage conditions.

LP38690DTX-2.5/NOPB is a versatile, efficient and cost-effective power management IC. It is suitable for a wide range of applications, offering a stable and adjustable output voltage that is adjustable from 2A to 10A. The integrated power MOSFETs, switching regulator and current limiter offer additional protection against overload and overvoltage conditions. The 8-pin NOPB package ensures that the IC can be easily mounted on any PCB, and makes it a suitable choice for a wide range of applications.
