Yes it appears to be the EN pin on the ISA1000A, see https://electronics.stackexchange.com/q/380475 On apq8026-lg-lenok there is a similar setup for the vibration motor although there I don't know whether it's actually a fixed-regulator or not, but since the two devices were built in a similar time (without checking further) I could assume they both contain the same IC.
