ST3M014/11
ELECTRICAL CHARACTERISTICS (Unless otherwise specified, please refer to the typical operating circut of the pag 1 for the external components values and connections. Unless otherwise noted SHDN =HIGH)
Note 1: For VIN < 1.9V the VO(LB) is out of regulation because of under dropout condition
Note 2: VO(DC/DC) = 3.5V force for an external DC source to avoid switching noise
