TPS7A7002负载电容与4G模块电源问题

Other Parts Discussed in Thread: TPS7A7002, TPS54232

4G模块需要的电压是3.8V,正常工作电流在250mA以下,由于瞬间电流能达到3A,因此模块厂家推荐在每个NB电源模块管脚上增加1个220uF电容,这样总电容负载为880uF。我的AC/DC模块输出的电压是5V。我打算使用TPS7A7002给模块供电,但TPS7A2002规格书上标明负载电容仅为220uF。请问是否有其它解决办法,例如电容放到TPS7A2002输入端,是否能像放到输出一样保持电流。还是需要更换其它芯片?谢谢!如果使用TPS54232给TPS7A2002供电,TPS54232能否这样的容性负载,谢谢!
