The PQ070XZ01ZZH is a voltage regulator from NXP, a leader in the development and manufacture of PMICs (Power Management Integrated Circuits). Voltage regulators are used to regulate the voltage in an electronic system, which is necessary for reliable and safe operation. The PQ070XZ01ZZH belongs to the linear voltage regulator family and is used to maintain constant output voltage even when input voltage changes. In this article, we will discuss the application field and working principle of the PQ070XZ01ZZH.The PQ070XZ01ZZH is primarily used in low-voltage applications, such as household electronics and automotive systems. It can be used to provide regulated power to discrete components, such as transistors and opamps, as well as integrated circuits. The PQ070XZ01ZZH is designed for a wide range of input voltages, from +3V to +18V, and can supply a load current up to 300mA. Its maximum output voltage is +5V, and its output error is 2.5% maximum.The PQ070XZ01ZZH is a three-terminal linear voltage regulator. Its input voltage, Vin, is applied to the input terminal while the regulated output voltage, Vout, is taken from the output terminal. The third terminal, called the ground terminal, is connected to ground. The circuit block diagram of the PQ070XZ01ZZH is shown in Figure 1. The internal components of the PQ070XZ01ZZH are an error amplifier, and a series pass element, the output current mirror, a temperature sensor and the series pass resistor and the feedback divider network.The working principle of the PQ070XZ01ZZH is based on the feedback control system. The output voltage is compared with the reference voltage by the error amplifier, and then the error voltage is applied to the internal circuits. The error voltage is amplified by the series pass element, and the amplified signal is compared with the reference voltage. If there is a mismatch, the output will be adjusted accordingly. The output voltage is regulated by the output current mirror that adjusts the output current with the feedback signal.When the input voltage is changed, the feedback signal is sent to the error amplifier and to the output current mirror. As a result, the voltage applied to the output current mirror is adjusted until the output voltage reaches the desired level. The series pass resistor limits the maximum current flowing through the output terminal, thus regulating the output. To allow the circuit to remain stable, a temperature sensor is used to monitor the internal temperature of the regulator and make adjustments as needed.In summary, the PQ070XZ01ZZH is a three-terminal linear voltage regulator used in low-voltage applications. It has a wide input voltage range from +3V to +18V, and its maximum output voltage is +5V. It uses a feedback control system to maintain stable output voltage even when input voltage changes. The internal components of the regulator are an error amplifier, a series pass element, an output current mirror, a temperature sensor and a feedback divider network.
