Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs. *5: SI-3000KFE 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 28 ICs SI-3000KF Series Block Diagram SI-3010KF Ta-PD Characteristics 20 With Infinite Heatsink Silicone Grease: G746 (Shin-Etsu Chemical) Heatsink: Aluminum Power Dissipation PD (W) VIN 2 4 VOUT 15 200x200x2mm (2.3C/W) 10 100x100x2mm (5.2C/W) 75x75x2mm (7.6C/W) VC 1 TSD - + 5 ADJ 3 GND 5 Without Heatsink 0 -30 -20 0 20 40 60 80 Ambient Temperature Ta (C) 100 REF Typical Connection Diagram SI-3010KF D1*1 VIN 2 + VO 4 R1 + CIN VC GND ADJ 1 5 3 *2 CO Load R2 R3 CIN: Input capacitor (22F or larger) CO: Output capacitor (47F or larger) If a low ESR capacitor (such as a ceramic capacitor) is used for the output capacitor, oscillation may occur. *1. D1: Reverse bias protection diode This diode is required for protection against reverse biasing between the input and output. (Sanken RU2Z is recommended.) R1, R2: Output voltage setting resistors The output voltage can be adjusted by connecting R1 and R2 as shown above. The recommended value for R2 is 10k. R1=(VO-VADJ)/(VADJ/R2) *2: Insert R3 in case of setting VO to VO 1.5V. The recommended value for R3 is 10k.
