LP3980/H
500mA,Ultra-low noise, Small Package Ultra-Fast CMOS LDO Regulator
概述
The LP2206 is a dual channel, low noise, and low dropout regulator sourcing up to 600mA at each channel. The range of output voltage is from 0.81V to Vin by operating from 2.5V to 5.5V input. LP2206 offers 2% accuracy, extremely low dropout voltage (280mV @ 400mA), and extremely low ground current, only 75μA per LDO. The shutdown current is near zero current which is suitable for battery-power devices. Other features include current limiting, over temperature, output short circuit protection. LP2206 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. LP2206 is available in fixed output voltages in the TDFN-8(2*2mm) and ESOP8 package.
