(Both modes can be selected by the LP9 signal.) It is designed to be integrated with other analog cells, digital logic, microcontrollers, DSP cores and memory blocks into system-on-chip products. The circuit consists of a PMOS pass device, an error amplifier and a feedback resistive network, sized to achieve the required closed loop gain. These blocks make up the regulating loop. An over-current and short circuit protection circuit has been included to limit the output current delivered by the regulator, thus avoiding destruction in case of a short circuit. An external reference voltage VBG (bandgap voltage) is necessary for correct functionality. The target reference voltage is 1.231V delivered, for example, by BG019. Double pads on the supply voltage VBAT1A/V BAT1AA and output voltage VCOREA/VCOREAA are used to reduce the total output resistance. Current reference is generated inside the cell through a circuit supplied by a 2.5V ± 0.1V of regulated input voltage on VSAUVC. Remote sense terminal VCORES provides regulation of the load by connecting it to the output terminal near a critical point to improve performance of the regulator (e.g., connecting it to the package pin by double-bonding, thus avoiding the bonding resistance influence). A ceramic capacitor of 2.2 µF connected from VCOREA/VCOREAA to ground is needed as external compensation.
