关于OPA549 Sink power supply的疑问

Other Parts Discussed in Thread: OPA549, OPA548

Hi ,TI的工程师们，

在看到DATASHEET PAGE12的PROGRAMMABLE POWER SUPPLY里面，说是

“A programmable source/sink power supply can easily be built using the OPA549. ”

请问OPA549可以吸收电流？？，能吸收多大电流，还是说我理解错了，

我不太懂sink power supply如何实现，请问TI的工程师是否有相关的资料分享，谢谢!
