SGM2079-ADJQ
SGM2079-ADJQ is Low Dropout Linear Regulator manufactured by SG Micro.
DESCRIPTION
The SGM2079x Q 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 130m V. The operating input voltage range is from 2.2V to 5.5V and output voltage range is from 0.8V to 5V.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2079x Q 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 SGM2079x Q is available in a Green TDFN-3×3-8JL package. It operates over an operating temperature range of -40℃ to +125℃.
