LP2201数据手册LPSemi中文资料规格书

描述 Description

The LP2201 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 from operating from 2.5V to 5.5V input. LP2201 offers 2% accuracy, extremely low dropout voltage (80mV @ 100mA), and extremely low ground current, only 25μA 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. LP2201 is short circuit thermal folded back protected. LP2201 lowers its OTP trip point from 165°C to 110°C when output short circuit occurs (VOUT < 0.4V) providing maximum safety to end users. LP2201 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. LP2201 is available in fixed output voltages in the SOT-23-6 package.
