n Standard External Circuit C 1: Oscillation prevention capacitor (approx. 0.33µF) Connection to terminal No.2 must be made as short as pos- sible. C 2: Output capacitor (47 to 100µF) Connection to terminal No.1 must be made as short as pos- sible. D 1: Protection diode (RM1Z) Required for protection against reverse biasing of input and output. Note 1: Connect a 47µF to 100µF capacitor to both sides of the load if the wiring between the output terminal and the load is long. Note 2: An isolation type diode is provided from input to ground and also from output to ground. These may be destroyed if the device is reverse biased. In this case, use a diode with low V F to protect them. Note 3: The output voltage may not be adjusted by raising the ground voltage (using a diode or resistor). l SI-3000P Series VIN VO D 1 C 2C 1 2 1 SI-3000P DC input DC output 0–20 0 25 50 75 100 Ambient Temperature Ta (°C) Power Dissipation PD (W) 75×75×2 (7.6°C/W) Without heatsink Without Mica With Silicon Grease Heatsink: Aluminum Unit: mm
