SGM2048C数据手册SGMICRO中文资料规格书

描述 Description

The SGM2048C is a low noise, high PSRR, low dropout voltage linear regulator. It is capable of supplying 1A output current with typical dropout voltage of only 150mV. The operating input voltage range is from 2.2V to 7V. The SGM2048C is available in fixed output voltage versions and an adjustable version that allows the output voltage range from 0.8V to 6V.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2048C has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2048C is available in a Green TDFN-3×3-8CL package. It operates over an operating temperature range of -40℃ to +125℃.
