GENERAL DESCRIPTION

The SGM4040 is a micro-power, precision shunt voltage

reference which is easy to use in many applications. It

has a fixed output voltage of 2.5V, and draws operating

current up to 15mA. The device has no need for external

capacitors and can keep stable with any capacitive load.

The SGM4040 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 SGM4040 offers high accuracy of 0.1% (MAX) for

A grade, 0.2% (MAX) for B grade, and 0.5% (MAX) for

C grade.

The SGM4040 is available in Green SOT-23 and

SC70-5 packages. It operates over an ambient

temperature range of -40℃ to +125℃.
