Working PrincipleThe working principle of the KD1084ADT-R is based on two operational amplifiers and two current regulators as the core components. The two operational amplifiers form a voltage regulator circuit. The first operational amplifier feeds back the dynamic output voltage to the error amplifier. The dynamic output voltage is converted to current by the second operational amplifier and then is output at the output voltage terminal according to the voltage difference. The two current regulators help to detect the voltage at the output voltage terminal. The detected voltage value is compared with the reference voltage, and the difference value is sent to the differential amplifier. The error amplifier adjusts the dynamic output voltage according to the comparison results, so that the output voltage is adjusted.ConclusionTo sum up, the KD1084ADT-R voltage regulator is a linear voltage regulator with high efficiency, low quiescent current, wide operating temperature range, and low ripple.
