UCC384DP-5 (TEXAS INSTRUMENTS)

The UCC384DP-5 is a low-dropout (LDO) Linear Regulator fabricated with a BCDMOS technology ideally suited for low input-to-output differential applications. The device passes 0.5A while requiring only 0.2V of input-voltage headroom. Dropout voltage decreases linearly with output current, so that dropout at 50mA is less than 20mV. Quiescent current consumption for the device under normal (non-dropout) conditions is typically 200µA. An integrated charge pump is internally enabled only when the device is operating near dropout with low VIN. This ensured that the device meets the dropout specifications even for maximum load current and a VIN of -3.2V with only a modest increase in quiescent current. Quiescent current is always less than 350µA, with the charge pump enabled. The quiescent current of the device does not increase with load current. Short-circuit current is internally limited. The device can be shutdown to 45µA (maximum) by pulling the SD/CT pin more positive than -0.7V.
