The UCC383TDKTTT-3 is a low-dropout (LDO) Linear Regulator fabricated with a BiCMOS technology ideally suited for low input-to-output differential applications. The device includes reverse voltage sensing that prevents current in the reverse direction. Quiescent current is always less than 650µA. This device have been internally compensated in such a way that the need for a minimum output capacitor has been eliminated. The output voltage is regulated to 1.5% at room temperature. Short-circuit current is internally limited. The device responds to a sustained overcurrent condition by turning off after a tON time delay. The device then stays off for a period, tOFF, that is 32 times the tON delay. The device then begins pulsing on and off at the tON/(tON + tOFF) duty cycle of 3%. This drastically reduces the power dissipation during short-circuit and means heat sinks need only accommodate normal operation.
