GENERAL DESCRIPTION

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℃.
