SGM2028

500mA, Ultra-Low Dropout,

Low Power, RF Linear Regulator

GENERAL DESCRIPTION

FEATURES

The SGM2028 is a low dropout voltage, low power and

low noise RF linear regulator. It is capable of supplying

500mA output current with typical dropout voltage of

only 270mV. The operating input voltage range is from

2.5V to 5.5V.

 Operating Input Voltage Range: 2.5V to 5.5V

 Fixed Output Voltages: 2.8V, 3.0V, 3.3V

 Adjustable Output Voltage Range: 1.2V to 5.0V

 500mA Guaranteed Output Current

 Output Voltage Accuracy: ±3% at +25℃

 High PSRR: 73dB (TYP) at 1kHz

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection.

 Ultra-Low Dropout Voltage:

270mV (TYP) at 500mA

 Low Output Noise: 30μV_RMS(TYP)

 Thermal Shutdown Protection

The SGM2028 is available in a Green SOT-23-5

package. It operates over an operating temperature

range of -40℃ to +85℃.

 Output Current Limit

 SGM2028-2.8, SGM2028-3.0 and SGM2028-ADJ:

110kΩ Pull Down Resistor at EN Pin

 SGM2028-3.3: No Pull Down Resistor at EN Pin

 -40℃ to +85℃ Operating Temperature Range

 Available in a Green SOT-23-5 Package
