APPLICATION INFORMATION
A supply bypass capacitor of 0.1 /C0109F is recommended. In most applications, the REF30xx does not require an output bypass capacitor. For the effects of a capacitive load on device performance, see Figures 8 and 9 in the Typical Characteristics section. Power Supply The REF30xx family of references works at supply voltages between 2.7 V and 5.5 V . The maximum dropout voltage in this range is 2.5 mV . While the power supply voltage rises to the specified level during power −up, the REF30xx will temporarily draw a higher than typical current. It is recommended to use a power supply with a fast rising edge. Line Regulation Line regulation is defined as the change in output voltage due to the change in the input voltage. For REF30xx, this change is less than 100 /C0109V/V across the specified supply voltage range. Thermal Hysteresis Thermal hysteresis is defined as the change in the output voltage after the device is cycled through the operating temperature range. This change is reported as a fraction of the nominal output voltage, in ppm. The initial output V PRE is measured at 25 °C. After the device is cooled to −40°C, heated to +80°C, then cooled back to 25°C, the final output voltage VPOST is measured. The thermal hysteresis is equal to ThHYST /C0043 /C0356VPRE /C0042VPOST/C0356 VNOM /C0064106(ppm) (eq. 1) where VNOM is the nominal output voltage. Temperature Drift Temperature drift is defined as the change in the output voltage caused by a change in operating temperature. (See Figure 2 in the Typical Characteristics section.) The REF30xx family is designed to exhibit a temperature drift of less than 50 ppm/°C across its entire operating temperature range of −40°C to +85°C. Noise Performance The noise generated by the REF30xx family is typically less than 50 /C0109Vp−p between frequencies of 0.1 Hz to 10 Hz, as shown in the Typical Characteristic Curves. Output noise can be additionally reduced using a low−pass filter, although care should be taken, as capacitive loads affect the PSRR and the output impedance. (See the Typical Characteristics section.) Load Regulation Load regulation is defined as the change in output voltage due to a specified change in load current. The REF30xx family can sink or source up to 10 mA of current, with an output change of less than 250 /C0109V/mA when sourcing, or 350 /C0109V/mA when sinking current.
