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 quickly 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℃.
