Patent ID: 11886215
Assignee: AMS AG
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 15:
16. A voltage regulator, comprising
an output transistor with a controlled section connected between a first supply terminal and an output terminal,
an amplifier comprising a reference input,
a current mirror comprising a replica transistor, wherein the current mirror is configured to mirror and attenuate a load current supplied by the output transistor to the replica transistor, and
a filter circuit coupled to a controlled section of the replica transistor and coupled to the output terminal, wherein
the output terminal is an NMOS transistor,
the current mirror comprises a diode-connected transistor such that the controlled sections of the diode-connected transistor and the replica transistor are electrically connected to each other's control sides, and
the output transistor is connected to a circuit node via the controlled sections of the output transistor.
