TPS51386: VCC as a power source

Part Number: TPS51386
Other Parts Discussed in Thread: TPS51383

Hello,

We're designing with the TPS51386 and wondering, can VCC LDO be used to power external circuitry?

If so, what is the output current capability?

Is VCC LDO always on, or is it disabled under certain conditions?

Thank you, Keith

    Hi 

    Not suggest to use VCC as LDO to power external circuit as its loading capability is limited.

    We have  TPS51393/5 ,TPS51383 which have 100mA loading capbility and its always on even when buck off, LDO is off when Vin < UVLO.

    BRs,
