LP3925: PSRR graph of LP3925 between 1KHz to 10MHz

Part Number: LP3925


I am planning to use LP3925 in one of my designs. I am planning to use buck regulators on LP3925 and then provide its output as input to the LDO. From datasheet I understand that switching frequency of buck regulators is around 2.5MHz - 3MHz. It is essential for me reject this switching frequency for my further stages. But the PSRR data is given at 10KHz only. I would like to know PSRR value over frequency range of 10KHz to 10MHz. This is important for my design. Hence I request you to provide PSRR graphs for various LDOs upto 10MHz.

Thanks & Regards,
