ICs
SI-3000KM Series
■Electrical Characteristics 2 (High VO type)
*1: Refer to the Dropout Voltage parameter.
*2: IS1 is specified at the 5% drop point of output voltage VO on the condition that VIN=overcurrent protection starting current, IO = 10 mA).
*3: Output is OFF when output control terminal (VC terminal) is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.
*4: SI-3010KM, SI-3050KM and SI-3090KM, SI-3120KM cannot be used in the following applications because the built-in foldback-type overcurrent protection may cause errors during
start-up stage.
(1) Constant current load (2) Positive and negative power supply (3) Series-connected power supply (4) VO adjustment by raising ground voltage
*5: VIN (max) and IO (max) are restricted by the relation PD = (VIN - VO)
× IO. Please calculate these values referring to the Copper Laminate Area vs. Power Dissipation data as shown
hereinafter.
