2 / 5 page 29 Parameter Input Voltage Output Voltage (SI-3025B: Reference Voltage) Dropout Voltage Line Regulation Load Regulation Temperature Coefficient of Output Voltage (SI-3025B: Temperature Coefficient of Reference Voltage) Ripple Rejection Quiescent Circuit Current Overcurrent Protection Starting Current*3,4 Control Voltage (Output ON) Control Voltage (Output OFF) VC Control Current Terminal*5 (Output ON) Control Current (Output OFF) qSI-3000B Series sElectrical Characteristics *1: VIN(max) and IO(max) are restricted by the relation PD(max)=(VIN-VO)•IO=14(W). *2: Refer to the dropout voltage.(Refer to Setting DC Input Voltage on page 7.) *3: IS1 is specified at –5(%) drop point of output voltage VO on the condition that VIN=VO+3V, IO=0.2A. *4: A foldback type overcurrent protection circuit is built into the IC regulator. Therefore, avoid using it for the following applications as it may cause starting errors: (1) Constant current load (2) Plus/minus power (3) Series power (4) VO adjustment by raising ground voltage *5: Output is ON even when output control terminal VC is open. Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an LS-TTL circuit. *6. When setting output voltage to 5V or less, input voltage needs to be set to 6V or over to operate stably.
