GENERAL DEscriptION

The SGM2036S is a low input voltage, low noise 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 0.75V to 5.0V in fixed output version. For adjustable output version, the output voltage can be adjusted from 0.8V to 5.0V by using external resistors.

Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2036S has automatic discharge function to discharge VOUT in the disabled status.

The SGM2036S 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℃.
