GENERAL DEscriptION
The SGM2056 is a high current, high PSRR, ultra-low noise and ultra-low dropout voltage linear regulator. It is capable of supplying 1.2A output current with typical dropout voltage of only 85mV. The operating input voltage range is from 1.1V to 7V. The adjustable output voltage range is from 0.8V to 5.5V by using an external resistor divider.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2056 has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2056 is available in a Green TDFN-3×3-8DL package. It operates over an operating temperature range of -40℃ to +125℃.
