Shutdown quiescent current
WebJul 16, 2024 · Off-the-shelf regulated charge pumps with output-current capabilities ≥10mA have typical minimum quiescent currents of 50 to 100µA. If that level of quiescent current is not acceptable, you can reduce the overall average by adding circuitry that monitors the regulated voltage remotely and toggles the charge pump in and out of shutdown. WebBest Answer. "Quiescent current" is the nominal (average) current used while "on" in a minimal state, such as an amplifier IC which is on and ready to work, but not currently …
