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℃.
