PQ1R38 is a type of linear voltage regulator manufactured by ROHM. It is designed for use in low-noise and high-efficiency applications such as switching power supplies, amplifiers, and microprocessors.

The PQ1R38 is a 3-terminal positive voltage regulator that can provide an output voltage as high as 2.5V and as low as 1.2V. It works by comparing an internal reference voltage to the output voltage, and can regulate an output current up to 500mA.

The device has a number of features that make it well suited to sensitive circuits. It is constructed with an advanced CMOS process that minimizes noise and power consumption, and it provides low dropout regulation to ensure that its output voltage remains constant even when its input voltage varies.

The PQ1R38 also offers a range of protective features such as over-voltage and over-current protection to keep circuits running safely. It is designed to operate over a wide range of temperatures, from -40°C to +125°C, and its high-speed internal protection features make it suitable for use in automotive applications.

The working principle of the PQ1R38 is relatively straightforward. It uses a negative feedback loop to compare the input voltage to the output voltage, and then adjusts the output voltage as needed to maintain a constant output voltage relative to the input voltage.

In short, the PQ1R38 is well suited for low-noise and high-efficiency applications that require stable output voltage. It has a number of features that make it attractive to applications such as switching power supplies, amplifiers, and microprocessors, and its range of protective features should make it suitable for automotive applications as well.
