SGM2078
SGM2078 is Low Power and Low Dropout RF Linear Regulator manufactured by SG Micro.
DESCRIPTION
The SGM2078 is a low input voltage, low noise, 1.2V logic supporting and low dropout voltage linear regulator. It is capable of supplying 300m A output current with typical dropout voltage of only 190m V. 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℃.
