GENERAL DESCRIPTION

The SGM2221 is a low quiescent current, low dropout

and high input voltage linear regulator. It is capable of

supplying 300mA output current with typical dropout

voltage of 330mV. The operating input voltage range is

from 2.2V to 13V and fixed output voltage range is from

1.8V to 5.0V.

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2221 has automatic discharge

function to quickly discharge VOUT in the disabled status.

The SGM2221 is available in Green SOT-23-5 and

TDFN-2×2-6AL packages. It operates over an operating

temperature range of -40℃ to +125℃.
