摘要:
In an embodiment, a linear voltage regulator includes: an output transistor having a first current path terminal configured to be coupled to a load, and a second current path terminal coupled to a first supply terminal, where the output transistor is configured to provide, at the first current path terminal, a regulated output voltage; a voltage source circuit configured to provide, in an open loop manner, a first voltage to a control terminal of the output transistor; and a feedback loop coupled between the first current path terminal of the output transistor and the control terminal of the output transistor, the feedback loop including a sense transistor having a first current path terminal coupled to the first current path terminal of the output transistor.
