Patent number: 9323264Abstract: A voltage regulator apparatus and an associated method are provided, where the voltage regulator apparatus includes: a voltage regulator module for regulating an input voltage according to a bandgap reference voltage to generate an output voltage; and a plurality of sensing modules. Ina situation where the output voltage abruptly decreases, a sensing module reduces, based on a variation amount of the output voltage, a decrement of the output voltage. In a situation where the output voltage abruptly increases, another sensing module reduces, based on another variation amount of the output voltage, an increment of the output voltage. In addition, yet another sensing module senses variation of the output voltage, converts the variation of the output voltage into a current signal, and applies the current signal to a control terminal within the voltage regulator module to indirectly control the output voltage.Type: GrantFiled: March 11, 2014Date of Patent: April 26, 2016Assignee: Faraday Technology Corp.Inventors: San-Yueh Huang, Wei-Lun Chen, Xiao-Dong Fei
