Part Number: TPS7A20

Can the TPS7A20 parts be used in parallel?.  i.e two in parallel to get 600mA

thanks

    Hi Stephen,

    Any LDO can be paralleled with a bit of effort.  The TPS7A20 does not have a feedback node or NR pin to connect to, so you are left with using ballast resistors to parallel this device.  Here is an App note which may be useful to you.

    We do have plenty of linear regulators which can supply 600 mA without the added complexity of parallel LDO's.  If you want, I can review our catalog of parts for a suitable device if you provide me with a list of key requirements.

    Thanks,
