Functional Block Diagram the operating temperature change, which can be calculated as Equation 1. the temperature range, and VOUT is the nominal output voltage. The maximum temperature drift of the TPR70 is 3 ppm/°C from −40°C to 125°C. and VOUT is the nominal output voltage.

The TPR70 features a low output noise voltage with a typical value of 2.5 μVPP at V NOM = 2.5 V under room temperature. The noise voltage is proportional to the output voltage and the operating temperature. The noise reduction (NR) pin provides additional filtering to further reduce the output noise. It is recommended to connect a 10-nF or greater capacitor from the NR pin to ground. TPR70 Low-Noise, Low-Drift, Precision Voltage Reference www.3peak.com 11 / 18 DA20231202A2

  • Both input and output capacitors must be placed as close to the pins of the device as possible.
  • It is recommended to bypass the IN pin to ground with a 1- μF to 10-μF capacitor in parallel with a 0.1- μF small ceramic capacitor. The loop area formed by the bypass capacitor connection, the IN pin, and the GND pin of the system must be as small as possible.
  • It is required to place a decoupling 1- μF to 50- μF capacitor at the output. A small 1- μF ceramic capacitor in parallel is recommended to filter the noise and improve the output transient performance. Layout Example DNC IN DNC GND NC NC OUT NR V REF To ADC
