GENERAL DESCRIPTION

The SGM4027 is a precision, low power, low noise and

low dropout voltage reference, which is designed to

offer low temperature drift and high initial accuracy

while consuming only 245μA (TYP) quiescent current.

The SGM4027 features high precision and low power

consumption. The combination of these characteristics

makes the device ideal for use in industrial applications,

such as transmitters of temperature and pressure. To

keep the stability and decrease the output noise of the

output voltage, a capacitor with the capacitance of 2μF

to 22μF should be added at the output pin of SGM4027.

For the typical operation, the power supply voltage

should be 0.2V beyond the VREF. Due to the advantage

of low dropout and low power dissipation, it is

recommended to use SGM4027 in portable and

battery-powered equipment.

The SGM4027 is available in a Green SOT-23 package.

It is specified over the extended industrial temperature

range of -40℃ to +125℃.
