Overview

PQ012GN01ZZH is a Linear Voltage Regulator from PMIC (Power Management Integrated Circuit). It is a single-channel, positive LDOs (Low Dropout Regulators) with output current up to 1A. It enables efficient power delivery to a variety of electronic.

Application Field

PQ012GN01ZZH is designed to provide a regulated output voltage in a wide range of power electronic applications such as portable electronic devices, Handheld terminals, Wearable devices, Automotive systems, etc. It can supply voltage to processors, memory, logic, analog, MHz and I/O components.

Working Principle

PQ012GN01ZZH works on the principle of linear voltage regulation. It is a type of voltage regulator that uses an integrated circuit with a series of resistors to regulate the output voltage. The operation of the regulator is based on an error amplifier. The error amplifier compares the output of the regulator with a reference voltage. If the outputs of the regulator and the reference voltage differ, the error amplifier will increase or decrease the control current of the regulator. The current is then fed to the resistor network, which adjusts the output voltage to match the reference voltage. The output voltage will remain at the reference voltage as long as the input voltage remains stable.
