PQ015EZ5MZZ is a linear voltage regulator typically used in PMIC (power management integrated circuits) applications. It is designed to deliver a steady output voltage of 5V with a maximum current of 25mA, while providing protection against overvoltage, overcurrent and thermal shutdown.

The PQ015EZ5MZZ is a low-dropout (LDO) regulator, meaning it can deliver a output voltage very close to the desired voltage even when its input voltage changes by a relatively large amount. The difference between the input and output voltage is known as its “dropout” voltage - the smaller this dropout is, the bigger the voltage regulation range of the regulator.

The PQ015EZ5MZZ is protected from overvoltage and overcurrent with two separate internal protection circuits. The overvoltage protection (OVP) circuit will shut down the device if its input voltage exceeds a predetermined value, while the short-circuit protection (SCP) circuit will shut it down if it detects excessive current draw. The device also features an internal thermal shutdown circuit (TSD) which will shut it down if it gets too hot.

In addition to these protection features, the device features current limiting and foldback current limiting. Current limiting ensures that the output current never exceeds the maximum specified value, while foldback current limiting senses the load resistance and will reduce the output current if it falls below a certain threshold. This helps to ensure a steady and reliable output voltage even as the load requirement changes.

The PQ015EZ5MZZ is a highly efficient linear regulator, with very low quiescent current drain. This means it can deliver steady output without wasting much power, making it ideal for battery-powered applications. Its wide input voltage range and protection features make it a good choice for tough operating environments.

The PQ015EZ5MZZ is an ideal choice for a wide range of PMIC applications, offering the best combination of performance, protection and efficiency. By utilizing its low dropout voltage, high efficiency and protection features, designers can ensure a reliable and steady output voltage for their designs.
