Identifying markings

PCB dev codes: reg28a
Other PCB markings: 0J13554

Notes:

1
Without included optional headers.
2
Note: the minimum startup voltage is 2.7 V, but the regulator can operate down to 1.3 V after startup.
3
Instantaneous. This is the rating for the switch, and regulator actively limits input current to this while boosting. Sustainable input current depends on input and output voltage and external conditions like ambient temperature and airflow.
