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℃.
