Plastic Mold Package Type (TO-3P) Flammability: UL94V-0 Weight: Approx. 6g Terminal Connections

C1: Oscillation prevention capacitor (approx. 0.33µF) Connection to terminal No.2 must be made as short as possible. C2: Output capacitor to 100µF) Connection to terminal No.1 must be made as short as possible. D1: Protection diode (RM1Z) Required for protection against reverse biasing of input and output. Note 1: Connect 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 VF to protect them. Note 3: The output voltage may not be adjusted by raising the ground voltage (using a diode or resistor).
