The SGM4051 is a micro-power, precision shunt voltage reference which is easy to use in many applications. The device is available in a fixed output voltage of 1.225V and an adjustable version. It draws operating current up to 12mA. The device has no need for external capacitors and can keep stable with any capacitive load. 

The SGM4051 features low temperature coefficient, low output noise, and low dynamic impedance. These characteristics enable the device to output stable voltage over a wide operating temperature and current range. 

The SGM4051 offers high accuracy of 0.3% (MAX) for B grade and 0.5% (MAX) for C grade. 

The SGM4051 is available in Green SOT-23 and SC70-5 packages. It operates over an ambient temperature range of -40℃ to +125℃.
