SGM2041数据手册SGMICRO中文资料规格书

描述 Description

The SGM2041 is an ultra-low noise, high PSRR and low dropout voltage linear regulator. It is capable of supplying 300mA output current with typical dropout voltage of only 50mV. The operating input voltage range is from 1.6V to 5.5V and output voltage range is from 0.75V to 4.35V.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2041 has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2041 is suitable for application which needs low noise and fast transient response power supply, such as power supply of camera module in smart phone, etc.
The SGM2041 is available in an ultra-thin Green WLCSP-0.64×0.64-4B-A package. It operates over an operating temperature range of -40℃ to +125℃.
