LP2202中文资料300mA, Dual Channel Ultra-Fast CMOS LDO Regulato数据手册LPSemi规格书

描述 Description

The LP2202 is a dual channel, low noise, and low dropout regulator sourcing up to 300mA at each channel. The range of output voltage is from 1.2V to 3.6V by operating from 2.5V to 5.5V input. LP2202 offers 2% accuracy, extremely low dropout voltage (220mV @ 300mA), 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. LP2202 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. LP2202 is available in fixed output voltages in the SOT-23-6 package.
