For loaded conditions, Figure 6 in the TypicalCharacteristicssectionshowsatypicaldropoutvoltageversusloadplot. 8.3.2 UsingtheTRIM/NRPin The REF50xxA-Q1 family of devices provides a very accurate voltage output. However, V can be adjusted to OUT reduce noise and shift the output voltage from the nominal value by configuring the trim and noise reduction pin (TRIM/NR, pin 5). The TRIM/NR pin provides a ±15-mV adjustment of the device bandgap, which produces a ±15-mV change on the V pin. Figure 25 shows a typical circuit using the TRIM/NR pin to adjust V .

Although this pin is not generally suitable for accurate temperature measurements, it can be used to indicate temperature changes or for temperature compensation of analog circuitry. A temperature change of 30°C corresponds to an approximate 79- mVchangeinvoltageattheTEMPpin. The TEMP pin has high output impedance (see the Functional Block Diagram section).
