GENERAL DESCRIPTION

The SGM4027A 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 SGM4027A 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

SGM4027A.

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 SGM4027A in portable and

battery-powered equipment.

The SGM4027A is available in a Green SOT-23

package. It is specified over the extended industrial

temperature range of -40℃ to +125℃.
