Self-calibrating, stable LDO regulator |
摘要 |
A substantially unconditionally stable LOD regulator includes has first and second current paths. The first current path provides a reference current. The second current path receives an input voltage for developing a differential current with respect to the reference current based on the input voltage. The second current path has a sense resistor for sensing the differential current. A first current source biases the first and second current paths. A third current path senses the differential current and develops the input voltage in response thereto to control the differential current. A second current source biases the second current path. A first voltage follower circuit receives a first voltage on a first side of the sense resistor to provide an analog voltage output, and a second voltage follower circuit receives a second voltage on a second side of the sense resistor to provide a digital voltage output.
