PQ018EH01ZZ, or PQ018, is a low-power, low-dropout linear regulator developed by Microchip to provide better system performance and cost savings. Linear regulators are used to supply a specific voltage regulated output current, thus ensuring that the output voltage remains constant regardless of changes in input voltage. The PQ018 series is designed to provide a regulated output voltage from 0.8V to 5.6V, with up to 1.8 Amps peak current and 80mV of dropout voltage.

The PQ018EH01ZZ\'s application field is mainly in providing stable output voltage for low-power applications such as battery-powered solutions, wearables,Portable electronics, IoT, power management systems and remote sensors. The device offers additional features such as synchronizable/synchronous operation, a quality factor, and low quiescent currents. This makes the PQ018E ideal for such applications.

The working principle of the PQ018EH01ZZ is that the voltage drop across the linear regulator is kept constant by an integrated voltage reference. The voltage is applied across the device\'s current-limiting resistor and then to its base terminal. When the voltage at the output exceeds its set point, the feedback loop causes the base current of the device to be increased, thus increasing its total current, and hence reducing the voltage at the output. This loop continues until the voltage at the output reaches its desired set point, at which point the regulator starts to maintain a constant voltage.

The PQ018EH01ZZ is a versatile linear regulator that provides excellent power management for a variety of applications. It provides low dropout voltage, low quiescent current, and adjustable output voltage. The device offers additional features such as synchronizable/synchronous operation, a quality factor, and low quiescent currents. All this makes the PQ018EH01ZZ an ideal choice for power management applications.
