Abstract:
1. A voltage regulator device for generating an output voltage based on an input voltage and a reference voltage, said device comprising: a pass transistor, a first replica transistor and a second replica transistor, wherein source ports of said pass transistor and said first and second replica transistors are coupled to said input voltage, a drain port of said pass transistor is coupled to said output voltage, and a gate port of said pass transistor is coupled to gate ports of said first and second replica transistors; a capacitor coupled to said input voltage and a drain port of said second replica transistor; a coupling circuit configured to couple current from a drain port of at least said first replica transistor to said gate ports of said first and second replica transistors, said coupling circuit further configured to control voltage on at least said drain port of said first replica transistor based on at least said reference voltage.
