Abstract:
1. A method for operating an electronic apparatus, the apparatus including an ASIC device, a linear regulator module configured to be optionally coupled to an external-to-the-ASIC device capacitor via a node and a capless regulator module coupled to an internal capacitance of the electronic product via the node, the capless regulator module including a low-power sub-module and a high-power sub-module, the high-power sub-module configured to provide a greater amount of electrical current than the low-power sub-module, the method comprising: applying power initially to the ASIC device via the node with the low-power sub-module of the capless regulator module to initiate ASIC device power-up; and detecting whether or not an external capacitance is coupled to the node.
