I'm using the bq25890 on my product to provide charging to a 2700mAh LiPo battery. In the effort of optimizing my system's power consumption in idle/standby mode i was investigating potential sources of power leakage. One thing i noticed is that the LDO output (VREGN) on the charger IC is pulsing in the absence of input voltage on VBUS.
These pulses are adding to the current draw from our battery. What's causing the LDO's instability at no load (red waveform if voltage on REGN output with only a battery connected)
