Hello,
I'm currently working on a power consumption model for a sensor node. The power management stage will be based on an ADP5092.
I'm planing to use the Reg_Out in LDO-only mode. I didn't found the Quiescent current for this case. The documentation only say "ultralow quiescent current".
Should I base my calculus only on the Figure 20 (BAT Leakage Current vs. BAT Voltage) ?
Is the Quiescent current provided in Table 1 of the datasheet sufficient to calculate power loss? I'm accustomed to LDO with a Iq who depend on the drawn current.
Thank you for reading.
Hi,
You can refer to the quiescent current of SYS pin with REG_D0=low and REG_D1=high that shows 750nA. It includes all the power consumption of the ADP5092. You can also roughly calculate the LDO Iq is…
