The device includes several innovative circuits to ensure excellent transient response. Dynamic biasing increases the IQ for a short duration during transients to extend the closed-loop bandwidth and improve the device response time during transients.
Adaptive biasing increases the IQ as the dc load current increases, extending the bandwidth of the control loop. The device response time across the output voltage range is constant because of the use of a buffered reference topology, which keeps the control loop in unity gain at any output voltage.
These features give the device a wide loop bandwidth during transients that ensure excellent transient response while maintaining the device low IQ in steady-state conditions; see the Application and Implementation section for more details.
