The PQ05RD21J00H voltage regulator belongs to the linear voltage regulator category of PMIC (power management IC). This particular regulator is designed to output any desired voltage ranging from 1.2V to 5.5V, required by the external device or circuit. It is a continuous, constant-current and constant-voltage power supply and is used in variety of end applications where relatively small and stable output voltage is needed.

The working principle of the PQ05RD21J00H voltage regulator can be outlined in two main parts. Firstly, the control section, which uses a special error amplifier as an integral part of the IC package. This amplifier allows for setting the output voltage to any desired level within the range of 1.2V to 5.5V through the external resistors connected at the PRE and SET pins of the PQ05RD21J00H.

Secondly, the current and voltage control section, where the output voltage is regulated through the internal pass element - MOSFET, operated in constant current and constant voltage modes. Whenever the load connected at the output port increases, the output voltage of the PQ05RD21J00H drops slightly below the nominal. This is when the pass element (MOSFET) conducts more current, according to the control section’s defined input set-point and brings the output port (load) to its nominal voltage.

In all, the PQ05RD21J00H is suitable for powering nearly any type of circuit or device requiring a small, stable and constant output voltage. It is being used in most of the electronic devices, including industrial, automotive and entertainment industries. The automotive industry uses the voltage regulator to power many of the sensors and electronic circuits located in the vehicle’s ECU, while the entertainment industry uses it to power and regulate the audio, video and radio equipment. The industrial industry makes use of the regulator to power and control the data acquisition systems and test equipment.

The PQ05RD21J00H voltage regulator is also suitable for powering and controlling personal computers, network routers, modems, hard disk drives and other peripheral devices. It is very reliable and efficient and is capable of providing a smooth and stable output voltage for extended duration without any change in the output voltage levels. This is one of the many reasons why the PQ05RD21J00H has become so popular in this field.

Overall, the PQ05RD21J00H voltage regulator is a very versatile device capable of outputting a precise, stable and reliable voltage level. Its application fields span across many different industries and its ease-of-use makes it a preferred choice among power engineers. Its distinctive features make it an ideal choice for even the most demanding power supply needs and it is no wonder why the PQ05RD21J00H has become an industry standard.
