TLV61220: The output voltage drops at very low load

Part Number: TLV61220
Other Parts Discussed in Thread: BQ25606

Hi Team,

In a customer's application, the TLV61220 is connected to the Sys pin of BQ25606 which outputs 4.2V from a lithium ion battery. The output voltage of TLV61220 drops when connected to the load as follows: 4.96V@3mA, 4.40V@5mA and 3.72V@10mA. They have tried connecting the VBAT pin of TLV61220 to a 5V power supply with the same result. What could be the cause of this issue? Please see the schematic diagram and PCB layout below for reference.

Regards,

Danilo
