TPS22918-Q1: Selection of Input/Output Capacitors and Static Current Issues

Part Number: TPS22918-Q1
Other Parts Discussed in Thread: TPS22918

1. Please help review the following circuit; 5510uPRE_3V3 is the front-end power supply of the system, with an output capacitor of 22uF * 4; Are there any issues with the selection of input/output capacitors and their impact?
2. Is there any relevant case where TPS22918 consumes 4mA of current when ON is at a low level? Or may it be related to the above issue?
