2 / 12 page 17 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. ■External Dimensions (TO252-5) (Unit : mm) Pin Assignment q VC w VIN e GND r VO t SENSE (ADJ for SI-3010KM/SI-3120KM) Plastic Mold Package Type Flammability: UL94V-0 Product Mass: Approx. 0.33g Unit V V mV mV V µA µA mV/ °C dB A V µA µA V Parameter Input Voltage Output Voltage (Reference voltage VADJ for SI-3010KM) Line Regulation Load Regulation Dropout Voltage Quiescent Circuit Current Circuit Current at Output OFF Temperature Coefficient of Output Voltage Ripple Rejection Overcurrent Protection Starting Current*2 Control Voltage (Output ON) Control Voltage (Output OFF) VC Control Current Terminal (Output ON) Control Current (Output OFF) Input Overvoltage Shutdown Voltage Ratings SI-3010KM (Variable type) SI-3050KM SI-3090KM SI-3120KM min. typ. max. min. typ. max. min. typ. max. min. typ. max. 2.4*1 *1 *1 *1 0.98 1.00 1.02 4.90 5.00 5.10 8.82 9.00 9.18 11.76 12.00 12.24 VIN=7V, IO=10mA VIN=7V, IO=10mA VIN=11V, IO=10mA VIN=14V, IO=10mA 30 30 54 72 VIN=6 to 11V, VIN=6 to 11V, IO=10mA VIN=10 to 15V, IO=10mA VIN=13 to 18V, IO=10mA IO=10mA (VO=5V) 75 75 135 180 VIN=7V, VIN=7V, IO=0 to 1A VIN=11V, IO=0 to 1A VIN=14V, IO=0 to 1A IO=0 to 1A (VO=5V) 0.3 0.3 0.3 0.3 IO=0.5A (VO=5V) IO=0.5A IO=0.5A IO=0.5A 0.6 0.6 0.6 0.6 IO=1A (VO=5V) IO=1A IO=1A IO=1A 600 600 600 600 VIN=7V, IO=0A, VC=2V VIN=7V, IO=0A, VIN=11V, IO=0A, VIN=14V, IO=0A, R2=10k Ω VC=2V VC=2V VC=2V 11 1 1 VIN=7V, VC=0V VIN=7V, VC=0V VIN=11V, VC=0V VIN=14V, VC=0V ±0.5 ±0.5 ±1.0 ±1.5 Tj =0 to 100 °C (VO=5V) Tj=0 to 100 °CTj=0 to 100°CTj=0 to 100°C 75 75 68 66 VIN=7V, VIN=7V, VIN=11V, VIN=14V, f=100 to 120Hz (VO=5V) f=100 to 120Hz f=100 to 120Hz f=100 to 120Hz 1.1 1.1 1.1 1.1 VIN=7V VIN=7V VIN=11V VIN=14V 2.0 2.0 2.0 2.0 0.8 0.8 0.8 0.8 40 40 40 40 VC=2V VC=2V VC=2V VC=2V –5 0 –5 0 –5 0 –5 0 VC=0V VC=0V VC=0V VC=0V 33 26 30 33 IO=10mA IO=10mA IO=10mA IO=10mA Symbol VIN VO (VADJ) Conditions ∆VOLINE Conditions ∆VOLOAD Conditions VDIF Conditions Conditions Iq Conditions Iq (OFF) Conditions ∆VO/∆Ta Conditions RREJ Conditions IS1 Conditions VC, IH VC, IL IC, IH Conditions IC, IL Conditions VOVP Conditions 6.60± 0.20 5.34± 0.20 0.50± 0.10 2.30± 0.20 0.50± 0.10 (1.00) MAX 0.70 12345 1.27 TYP 1.27 TYP SEATING PLANE 0.00 to 0.127 0 to 8° 6.60± 0.20 5.34± 0.20 (5.04) (1.50) 0.50± 0.10 2.30± 0.20 0.1 |
