Working Principle
The TPS70848PWP is a low quiescent current, low dropout linear voltage regulator, designed to convert an input voltage of 2.7V to 6V to a fixed output voltage of 1.8V. The device operates by regulating the voltage drop between the output and the input. This regulation is achieved through a series pass transistor that is controlled by an adjustable bandgap reference voltage.
The bandgap reference voltage is generated by the on-chip reference generator and the output voltage is adjusted by connecting an external resistor divider to the pin marked FB (feedback). When the FB pin voltage matches the internal bandgap voltage, the output voltage is regulated at a fixed level. When the input voltage is higher than the output voltage + dropout voltage, the regulator will supply the load current.
The regulator has several protection features such as over-temperature protection, over-current protection and reverse current protection. The TPS70848PWP also has a power-save mode that reduces the quiescent current to less than 10μA when the load current is less than 10 mA.
