SGM2221

300mA, 0.9μALow Quiescent Current,

Low Dropout and High Voltage Regulator

GENERAL DESCRIPTION

FEATURES

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.

 Operating Input Voltage Range: 2.2V to 13V

 Fixed Outputs of 1.8V, 2.8V, 3.0V, 3.3V, 3.6V,

3.9V, 4.0V, 4.1V, 4.2V and 5.0V

 Adjustable Output from 0.8V to 5.0V

 Low Power Consumption:

0.9μA (TYP) at No Load

 Low Dropout Voltage:

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2221 has automatic discharge

function to quickly discharge V_OUTin the disabled status.

330mV (TYP) at 300mA, V_OUT= 5V

 Current Limiting and Thermal Protection

 With Output Automatic Discharge

 Stable with Small Case Size Ceramic Capacitors

 Shutdown Supply Current: 0.2μA (TYP)

 UVLO with Hysteresis

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℃.

 Reverse Current Protection when V_OUT> V_IN

 -40℃ to +125℃ Operating Temperature Range

 Available in Green SOT-23-5 and TDFN-2×2-6AL
