LDO noise is defined as the internally-generated intrinsic noise created by the semiconductor circuits. The TPS7H1121 output noise is typically 35μVRMS.
When an external compensation network is connected to the STAB pin, the applied network can reduce the loop bandwidth; therefore, the internal circuitry is less capable to minimize internally generated noise. Figure 6-20 shows the noise performance difference when configured with and without an external compensation network (note: RComp = 20kΩ and CComp = 1nF).
