Over-current protection in linear regulators |
摘要 |
An integrated circuit radio transceiver and method therefor includes a linear regulator an output transistor for producing a current into an output node of the regulator wherein an amplification block is operable to produce a bias signal to a gate terminal of the output transistor to operably bias the output transistor to produce the current into the output node of the regulator. A current steering amplification block is operably disposed to steer current in/out of the gate of the output transistor (depending on device type) based upon the current being conducted through the output node of the regulator exceeding a specified threshold. The current steering amplification block further includes a current sinking element operably disposed to sink a specified amount of current to define the specified threshold.
