您们好，TI专家们！
我对TPS51200数据手册关于输出电容的描述感到很疑惑。
如果 ESR 大于 2 mΩ，应在输出和 VOSNS 输入之间插入一个 RC 滤波器以实现环路稳定性。我用您们的模型来验证，发现调大ESR后，电路的相位裕度反而会增加。一般来讲输出电容的ESR越大，电路应该越稳定。
以下数据手册原文：
8.2.2.3 Output Capacitor
For stable operation, the total capacitance of the VO output pin must be greater than 20 μF. Attach three, 10-μF
ceramic capacitors in parallel to minimize the effect of equivalent series resistance (ESR) and equivalent series
inductance (ESL). If the ESR is greater than 2 mΩ, insert an RC filter between the output and the VOSNS input
to achieve loop stability. The RC filter time constant should be almost the same as or slightly lower than the time
constant of the output capacitor and its ESR
以下是仿真原理图和仿真结果：
