PQ070VK01FZH Application Field and Working Principle

PMIC - Voltage Regulators - Linear: PQ070VK01FZHMore and more devices are powered by batteries and need a regulated voltage output to maximize battery life. To meet the demand in this requirement, NXP Semiconductors has created PQ070VK01FZH as a linear voltage regulator. It is designed to provide up to 70 mA of dependable current regulate and is suitable for use in a variety of audio, handset and general purpose applications. PQ070VK01FZH is designed to provide a regulated voltage output ranging from 1V to 6V with minimal external components. A proprietary voltage regulation scheme ensures that the output voltage of the device is stable over all temperature conditions, load currents and battery discharges. The device can detect and protect against over current, under current, and overvoltage conditions which gives it an edge over other voltage regulators. PQ070VK01FZH is a low dropout linear regulator with internal circuit protection. It regulates by controlling constant voltage through setting a current through a resistor. When this current is set to the voltage at the regulator’s reference terminal, the output voltage is maintained. The output of the regulator is not twisted in this form, therefore it will be less affected by noise or other disturbances. To minimize dropout voltage across its output, the internal power transistor is driven in high current mode. The PQ070VK01FZH provides an adjustable output range of 0.9V to 6V, with an input voltage range of 2V to 6.5V. It has a typical quiescent current of 8μA and a typical dropout voltage of 140mV at 70mA. It has a shutdown mode to reduce power consumption when required. The device is manufactured using SOT-23-5 package and it is available in a variety of white, green and blue colored packages. The main applications of PQ070VK01FZH device is as a regulated voltage source in applications like: - Security systems- Wireless and other networking systems- Automotive systems- Wearable and Consumer electronics- Industrial equipment- Radio transmission equipmentIn a nutshell, PQ070VK01FZH is a low dropout linear regulator used for providing a regulated voltage output ranging from 1V to 6V with minimal external components. This device has an adjustable output range of 0.9V to 6V, and an input voltage range of 2V to 6.5V. It has good protection against over current, under current and overvoltage conditions, making it well suited for a variety of applications.
