UCC284-EP 增强型产品单路输出 LDO、500mA、固定电压 (5V)、低静态电流、宽输入电压范围

The UCC284-x family of negative linear-series pass regulators is tailored for low-dropout applications where low-quiescent power is important. Fabricated with a BCDMOS technology ideally suited for low input-to-output differential applications, the UCC284-x passes 0.5 A while requiring only 0.2 V of input-voltage headroom. Dropout voltage decreases linearly with output current, so that dropout at 50 mA is less than 20 mV.

Quiescent current consumption for the device under normal (non-dropout) conditions is typically 200 µA. 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
