As far as “Zero Quiescent Current” Linear Regulator is concerned, the working principle revolves around maintaining constant voltage levels by making use of an integrated amplifier, which functions on feedback control. In other words, the stability of the desired output voltage is based on the negative feedback feature in an amplifier. Based on the amount of external load on the DC voltage, the amplifier automatically adjusts the power supply output current. In order to reduce the impact of the parasitic effects in an amplifier, the amplifier uses an operational feedback to maintain constant voltage levels.

At the same time, the device implements a number of protection mechanisms such as over-voltage, over-current, reverse-current and thermal protection. These protection functions are completely automated. In addition, the device provides an adjustable soft-start feature to help protect the system from inrush current.

In conclusion, TPS658642ZQZT is an ideal PMIC for power management applications. It has a wide input voltage range and is capable of providing precise current and stable output voltage. It also features low quiescent current, power sequencing, low power operation and integrated power-on/power-off control. In addition, the device provides various protection features and an adjustable soft-start feature for system protection. All these features make it ideal for use in a variety of applications, including smartphones, tablets, digital cameras, GPS and gaming systems.
