7.3.9 REF (Voltage Reference)

The 5-V ± 1.2% reference supplies power to internal circuitry, and also supplies up to 5 mA to external loads. The reference is shutdown during undervoltage lockout but is operational during all other disable modes. For best performance, bypass with a 0.1-μF low-ESR low-ESL capacitor to GND. To ensure the stability of the internal reference, do not use more than 1 μF of total capacitance on this pin for the UCC1895.

For the UCC2895 and the UCC3895, this capacitance increases as per the limits defined in the Recommended Operating Conditions of this specification.
