Источники Опорного Напряжения или Тока (ИОНиТ) LM4040BEX3-2.5+

Источник опорного напряжения с шунтом - фиксированный , 2.5В, ±100млн-1/°C, SC-70-3

The LM4040BEX3-2.5+ is an improved precision micropower shunt voltage reference in 3 pin SC-70 package. This two terminal shunt mode band gap voltage reference is ideal for space critical applications. The laser trimmed resistors ensure precise initial accuracy of 0.2% with ±100ppm/°C maximum temperature coefficient value (IR = 1mA). The LM4040B has 45µA minimum shunt operating current capability with low dynamic impedance which ensures stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents. This device does not require an external stabilizing capacitor while ensuring stability with any capacitive load.

• Fixed reverse breakdown voltage of 2.5V
• Operating temperature range from -40°C to 125°C
• Low wideband output noise of 35µVrms (10Hz to 10KHz, IR=100µA)
• Reverse breakdown voltage tolerance of ±4mV
• Reverse dynamic impedance of 0.3ohm (IR = 1mA, f = 120Hz, IAC = 0.1IR)
• Reverse breakdown voltage long term stability of 120ppm at T = 1000h
