Abstract: An electronic circuit includes parallel linear regulator circuits that support a range of different load currents. The electronic circuit includes a first linear regulator circuit coupled to an output node, a second linear regulator circuit coupled in parallel with the first linear regulator circuit and the output node, and a control circuit. The control circuit is configured to monitor the output node and to suppress or inhibit the second linear regulator circuit from supplying the output node when a representation of load power consumption is below a specified threshold. The first linear regulator circuit is configured to continue to supply a portion of the load power when the representation of load power consumption is above the specified threshold, and the control circuit may disable the second linear regulator circuit when the representation of load power consumption is below the specified threshold.

Abstract: A device to detect an electrical signal is provided. The device includes sensing, output, and pull-down nodes. The device includes a pull-down circuit having a native metal-oxide-semiconductor field-effect transistor (MOSFET) to pull down the output node to approximately a voltage of the pull-down node. The device includes a switch circuit having a junction field-effect transistor (JFET). The JFET turns on the pull-down circuit in response to a voltage of the sensing node being less than a first threshold. The JFET also turns off the pull-down circuit in response to the voltage of the sensing node being greater than the first threshold.
