Источники Опорного Напряжения или Тока (ИОНиТ) LM4050CEX3-3.3+T

Источник опорного напряжения , шунт - фиксированный, LM4050, 3.3В, 0.5%, ±15млн-1/°C, SC-70-3

The LM4050CEX3-3.3+T from Maxim Integrated Products is a 50ppm/°C precision, micropower, shunt voltage reference with multiple reverse breakdown voltages in 3 pin SC-70 package. It is a precision two terminal, shunt mode, bandgap voltage reference with fixed reverse breakdown voltage of 3.3V. The laser trimmed resistors ensure excellent initial accuracy of 0.5% with a ±50ppm/°C temperature coefficient. The LM4050CEX3-3.3+T has a 60µA to 15mA shunt current capability with low dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperature and current. It is ideal for space critical applications. Typical applications include portable battery powered equipment, notebook computers, cell phones and industrial process controls.
