**Part Number:**LM53603-Q1

Hello,

I'd like to accurately estimate the Max dropout voltage of LM53603-Q1 under the following conditions.

- Output voltage drops down to 4.95 V.
- Output current: 3 A
- Switching frequency: It is acceptable that f
_{SW}goes below 1.85 MHz.

Alternatively, the worst case of Figure 25 (Drop-out for -1% Regulation) on the data sheet is OK.

Is there any equation or tool to calculate the number? Or, is actual measurement needed to get the number?

Please give me advice.

Best regards,

Shinichi Yokota
