The SGM2078 is a low input voltage, low noise, 1.2V logic supporting and low dropout voltage linear regulator. It is capable of supplying 300mA output current with typical dropout voltage of only 190mV. The operating input voltage range is from 1.6V to 5.5V. The output voltage range is from 0.8V to 3.3V in fixed output versions. For adjustable output version, the output voltage can be adjusted from 0.8V to 5.0V by using external resistors.
Other features include 1.2V logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2078 has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2078 is available in Green XTDFN-1×1-4L, SOT-23-5 and SC70-5 packages. It operates over an operating temperature range of -40℃ to +125℃.
