Abstract: Disclosed are various embodiments for compliance detection using natural language processing. Various embodiments include a computing device that can transcribe a sound recording of a transcript, where the sound recording can be representative of a telephonic call occurring between an agent and a client.

Abstract: A voltage regulator includes a first transistor including a first terminal to receive an input voltage and a second transistor including a first terminal coupled to a second terminal of the first transistor. A charge pump couples to the second transistor and to an output voltage node. An amplifier receives a feedback voltage derived from the output voltage and generates a control signal to gates of the transistors. Responsive to the input voltage being more than a threshold larger than the output voltage, the amplifier maintains the second transistor off and the first transistor on such that current flows through the first transistor to the output voltage node but not the second transistor. Responsive to the input voltage being less than the threshold amount, the amplifier operates the first transistor in a triode mode and turns on the second transistor to provide current to the charge pump.
