CO: Output capacitor (10

µF or larger)

The SI-3000LUS series can be operated on the circuit

even if a low ESR ceramic capacitor is used as the

output capacitor.

CIN:Input capacitor (0.1 to 10

µF)

This capacitor is required in the case of an inductive

input line or long wiring.

• A monolithic IC is mounted. The inner frame stage is con-

nected to the GND pin (pin 2). Therefore, enlarging the

copper laminate area leading to the GND pin achieves a

heat radiation effect.

• How to calculate the junction temperature

Measure the temperature (TC) of the GND pin (pin 2) lead

section using a thermistor, etc. Substitute this value in the

following formula and calculate the junction temperature.

Tj=PD

×θj–c+Tc (θj–c=5°C/W)
