SGM2085xQ
Automotive GradeAutomotive, 300mA, Low Noise, High PSRR, Low IQ and Low Dropout Regulator
The SGM2085xQ is an ultra-low noise, high PSRR and low dropout voltage linear regulator. It capable of supplying 300mA output current with typical dropout voltage of only 175mV. The operating input voltage range is from 1.9V to 5.5V and output voltage range is from 0.75V to 5.0V.
Other features include 1.2V logic-controlled shutdown mode, under-voltage lockout, short-circuit current limit and thermal shutdown protection. The SGM2085xQ has automatic discharge function to quickly discharge VOUT in the disabled status.
This device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM2085xQ is available in a Green SOT-23-5 package. It operates over an operating temperature range of -40℃ to +125℃.
