PQ070XF02SZH

The PQ070XF02SZH is a linear voltage regulator from Panasonic Semiconductor Solutions\'s MLCC Series of PMIC products. It is manufactured in a miniature, low-dissipation, 14-ball LGA (leadless grid array) package, and its main role is to provide an overall stable output voltage for a given input voltage.

The PQ070XF02SZH is designed to supply a regulated output voltage for a wide variety of applications, ranging from low power computing and embedded systems to industrial and automotive applications. The PQ070XF02SZH provides a regulated output voltage of 8.0V ±0.15 in a wide temperature range of -40˚C to +105˚C. With a wide input voltage range of 4.5V to 18V, the PQ070XF02SZH can also be used in distributed power systems.

The PQ070XF02SZH uses an internal voltage reference and error amplifier architecture that provides for higher input voltage and line transient tolerance. It uses low RDS (on) MOSFETs as the load regulator, providing lower power consumption and a better heat dissipation capability. The device also includes integrated protection features such as over-current, over-temperature and over-voltage protection. Other features include output accuracy, low-noise, low output voltager ripple and a fast transient response.

The working principle of the PQ070XF02SZH is as follows: When an input voltage is applied to the device, it is regulated by the internal voltage reference and error amplifier architectures, then is output to the load. The output voltage is further regulated with a feedback control loop that compares the output voltage to the reference voltage. If the output voltage is too high, the error amplifier reduces the MOSFET drive and current, and vice versa if it is too low. The device also includes other protection circuits to protect against current and temperature overload, ensuring the device is not damaged.

Overall, the PQ070XF02SZH offers a reliable voltage regulator solution for applications where a stable output voltage is critical. It provides excellent protection from current and temperature overload as well as a fast transient response to varying load current demands. It is also compatible with a wide input voltage range and has excellent temperature, voltage, and line transient tolerance due to its onboard voltage reference and error amplifier architecture.
