ADP3303属于ADP330x系列精密低压差
anyCAP® regulator,采用新颖的架构、改良的工艺和新封装,与传统LDO相比性能更出色。它采用专利设计,仅需一个0.47 µF输出电容便可保持稳定。这款器件使用任何电容均可稳定工作,与电容的ESR(等效串联电阻)值无关,包括适合空间受限应用的陶瓷型(MLCC)电容。ADP3303在室温条件下可达到±0.8%的出色精度,温度、线路和负载调节的整体精度为±1.4%。200 mA时,其压差仅180 mV(典型值)。
In addition to the new architecture and process, Analog Devices' new proprietary thermal coastline package can handle 1 W of power consumption without the need for an external heat sink or large area of copper on the printed circuit board. This minimizes the printed circuit board area, making it attractive for portable devices.
ADP3303 has a wide input voltage range (3.2 V to 12 V) and provides a load current of over 200 mA. The device has an error flag that displays information when the device is about to undergo an offset, or when short-circuit, thermal overload protection is activated. Other features include shutdown and optional noise cancellation. The ADP330x anyCAP® LDO series offers a wide output voltage range with output current levels from 50 mA to 200 mA:
ADP3300 (50 mA, SOT-23)
ADP3301 (100 mA)
ADP3302 (100 mA, dual output)
