SGM2205

800mA, High Voltage, Low Noise

and Low Dropout Voltage Regulator

GENERAL DESCRIPTION

FEATURES

The SGM2205 is a high voltage, low noise and low

dropout voltage linear regulator. It is capable of

supplying 800mA output current with typical dropout

voltage of only 450mV. The operating input voltage

range is from 2.5V to 20V.

● Wide Operating Input Voltage Range: 2.5V to 20V

● Fixed Outputs of 1.8V, 2.5V, 3.0V, 3.3V, 3.6V, 4.2V,

5.0V and 12V

● Adjustable Output from 1.8V to 15V

● Output Voltage Accuracy: ±1% at +25℃

● Low Dropout Voltage: 450mV (TYP) at 800mA

● Current Limiting and Thermal Protection

● Excellent Load and Line Transient Responses

● With Output Automatic Discharge

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2205 has automatic discharge

function to quickly discharge V_OUTin the disabled status.

● No-Load Stability

The SGM2205 is available in Green SOT-89-3, SOT-223-3,

SOIC-8, TDFN-3×3-8L and TO-263-5B packages. It operates

over an operating temperature range of -40℃ to +125℃.

● -40℃ to +125℃ Operating Temperature Range

● Available in Green SOT-89-3, SOT-223-3, SOIC-8,

TDFN-3×3-8L and TO-263-5B Packages
