... Application Notes When LDO is used in handheld products, Attention must be paid to voltage spike which would damage SG2001. In such applications, voltage spike will be generated at changer interface and V interface when changer adapters and USB equipments are hot-inserted. Besides this, handheld products will be tested on the production line on the condition of no battery. Test Engineer will apply power from the connector pin which connects with positive pole of the battery ...
