MIC5207-5.0BM5TR LDO电压调整器/稳压电源IC 5V 165mV/0.165V 带使能脚EN/CE SOT-153/SOT23-5 marking/标记 短路保护 过热保护
General Description
The MIC5207 is an efficient linear voltage regulator with ultra-low-noise output, very low dropout voltage typically 17mV at light loads and 165mV at 150mA, and very low ground current 720µA at 100mA output. The MIC5207 offers better than 3% initial accuracy.
Designed especially for hand-held, battery-powered devices, the MIC5207 includes a CMOS or TTL compatible enable/shutdown control input. When in shutdown, power consumption drops nearly to zero.
Key MIC5207 features include a reference bypass pin to improve its already low-noise performance, reversed battery protection, current limiting, and overtemperature shutdown.
