TPS7A4701-EP: Sink current

Part Number: TPS7A4701-EP

HI TI,

I am using TPS7A4701RGWR for RF application, where I generate 28V from 28.5V.

This RF circuit has few Pin diode Switches. Since I have PIN DIODE this LDO might have to sink -100mA current,

So what is the sink current capability of TPS7A4701RGWR??

    Hi Pradeep,

    Most positive LDO's only have the ability to source current. They do not normally have the ability to sink current. If VOUT happens to be higher than the intended regulation voltage, the LDO simply stops sourcing current to the load. 

    I hope this answers your question.
