11. Application information
11.1 Noise
The output noise is determined by the value of the output capacitor (see Table 7).

11.2 Stability
For stable operation:
• The maximum output capacitor ESR should not exceed 22 Ω (worst-case) and for the
minimum ESR, see Table 8.
• The ESR of the output capacitor is limited.
• See Table 8 for the minimum ESR values of the output capacitor, at Tamb given the
load and output capacitance.
