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 1.2V 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℃.
