TPS7A03: output discharge

Part Number: TPS7A03
Other Parts Discussed in Thread: TPS7A20, , TPS7A02

I am a little confused by the TPS7A03 (and also TPS7A02 and TPS7A20) datasheets. 

  • Section 7.2, the block diagram says "active discharge P-version only".
  • Section 7.3.2 Active Discharge (P-version only) describes the active discharge.
  • Section 7.4.4 Disabled says the output voltage is actively discharged, but no mention of "P only", so not clear what is the case. 
  • Table 3 in Section 11.1.1, it states, "P indicates an active output discharge feature. All members of the TPS7A03 family actively discharge
    the output when the device is disabled."  The second sentence seems inconsistent with the first, and also inconsistent with the preceding sections.

I am trying to find an alternative to the TPS7A2433 because I cannot find them to buy.  It is for use in a circuit where it will supply power from an external source, but if there is no external power the output will be powered from a battery (through a diode). If I were to use a non-P version of the TPS7A03, would I have a discharge situation?  I need low current (single digit uA) to prolong battery life.

This is the present TPS7A2433 circuit with external power coming from the left and the system voltage on the right.

Thanks,
