The PQ025EH01ZZH is an adjustable 6V – 25V linear voltage regulator that belongs to the family of PMIC (Power Management ICs) – Voltage Regulators – Linear. This regulator provides ultralow dropout voltage and low quiescent current, making it ideal for high efficiency applications where the minimum load is low. It features an adjustable output voltage and offers a dual output mode for higher power applications. Additionally, it includes protection circuitry for thermal overload, reverse polarity, output voltage higher than input voltage and overcurrent. The PQ025EH01ZZH voltage regulator works by controlling the amount of current that flows from the input voltage source to the output. This is done by two transistors, one placed between the input and output, and the other in series between the output and ground. A voltage divider is used to monitor the output voltage, and a circuit within the IC adjusts the current that flows through the two transistors. The amount of current allowed to flow is proportional to the voltage output desired. As the amount of current increases, the voltage output increases as well. The PQ025EH01ZZH linear regulator is used in a wide range of applications such as automotive power supplies, industrial power systems, telecom power systems, medical device power, general-purpose low voltage power supplies, and other power management applications.

The PQ025EH01ZZH is attractive due to its wide adjustable output voltage range from 6V to 25V, which allows it to be used in multiple applications. It has a low dropout voltage of 0.7V, a quiescent current of 10 uA, and an adjustable output current of up to 3A. This regulator also features a programmable output voltage rather than a fixed output voltage, allowing it to adjust to the voltage required by the application. With its high power efficiency, the PQ025EH01ZZH can operating with low losses.

The PQ025EH01ZZH linear voltage regulator has a wide range of protection features to ensure safety and stability. It features a thermal overload protection, which prevents the regulator from overheating by reducing the output current if the junction temperature reaches overheating temperatures. This also helps to protect any connected components from possible damage due to excessive heat. It also includes reverse polarity protection, which prevents damage to the device and other components in case the input voltage is connected to ground. Another feature is an overvoltage protection, which prevents the output voltage from exceeding the input voltage. Finally, it also includes an overcurrent protection, which will shut off the output current if the current draw exceeds the specified limit.

The PQ025EH01ZZH linear voltage regulator has a wide range of applications, from small consumer devices to automotive and industrial power systems. Its low dropout voltage and low quiescent current make it an ideal choice in high efficiency applications. Its protection features ensure safety and stability, while its wide adjustable output voltage range allows it to be used in multiple applications. With its high power efficiency, the PQ025EH01ZZH can operating with low losses and make it an ideal choice for reliable power management.
