Appeal No. 2003-0258
Application 09/684,138
THE INVENTION
The appellant claims a low drop-out voltage regulator
circuit that includes a class A output stage and a speedup
circuit therefor. Claim 5 is illustrative:
5. A low drop-out voltage regulator circuit comprising:
a MOS pass through transistor;
a resistor feedback circuit coupled to the MOS pass through
transistor;
an amplifier having an input coupled to the resistor
feedback circuit;
a Class A output stage coupled between an output of the
amplifier and a gate of the MOS pass through transistor; and
a speedup circuit coupled between the output of the
amplifier and the gate of the MOS pass through translator.
THE REFERENCE
Rincon-Mora et al. (Rincon-Mora) 6,046,577 Apr. 4, 2000
THE REJECTIONS
The claims stand rejected as follows: claim 5 under
35 U.S.C. § 102(a) as anticipated by Rincon-Mora, and claims 6-9
under 35 U.S.C. § 103 as obvious over Rincon-Mora.
OPINION
We reverse the aforementioned rejections.
