Even in the event of large power supply variations, this LT1431CZ#PBF voltage reference power management device from Linear Technology can produce and maintain a precise DC voltage. With an output that has a voltage of 2.5 to 36 V, this is power management at its best. It has an initial accuracy of 0.4%. Use this part at voltages lower than 36 V. This voltage reference circuit supports shunt topology. This voltage reference circuit has a minimum operating temperature of 0 °C and a maximum of 70 °C. It runs with a maximum temperature coefficient of 30ppm/°C(Typ).
